Installing a new Vertical ham Radio Antenna. Post 2057.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=IrWLqixFFuc

This video from "learnelectronics" takes us step-by-step in the assembly, tuning, and use of the popular Hustler 4BTV HF Antenna. 

Please note how carefully the antenna is laid out prior to assembly and how protectants, such as anti-seize compound, are used to protect joints, screws, bolts, and nuts.

A carefully planned assembly routine is vital if you hope to build this antenna right the first time.

How to use an antenna analyzer. Post 2055.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=bXp7uin7_7Y.

Over the past few years, I've found an antenna analyzer a most valuable tool for designing, building, and using homebrew antennas.  Although my MFJ-259 is several seasons old, it does what it's supposed to do.

In this well-made video from Ron Payne (WA6YOU), we get an excellent overview of what an antenna analyzer does and what are some of the shortcomings of the commercial products available.

This presentation was given before members of the Vienna Wireless Society on 28 April 2017.

Ron does a good job of explaining antenna analyzers in simple, easily understood terms.  As you may expect, there are several commercial versions of this useful tool available through the internet or from local Amateur Radio stores.

N4LQ Multiband Inverted L Antenna. Post 2053.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=uuD2mBZKHOg.

If you live on a small urban lot and want a fairly efficient multiband HF antenna covering 160 meters through 10 meters, then this video from N4LQ might be helpful.

As originally designed, the inverted L measured 100-feet/30.48 meters and used a MFJ-998 antenna "tuner" to control the mismatch found on the antenna.  Later, N4LQ extended the antenna length to 200-feet/60.97 meters and got better results.

The key to this antenna is to get as much vertical wire in the air as possible before adding the inverted L section at the top. Be sure to install a basic ground radial or counterpoise system to complete the project.

Ham radio HF stealth dipoles ON-AIR test and review


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=7rujoKVOhK8.  This is post 2052 in a continuing series about Amateur/Ham Radio Antennas.

Operating your amateur/ham radio station in deed-restricted housing can present difficult challenges. Rather than surrender to restrictive rules and regulations, why not be creative and make antennas that are nearly invisible, while still delivering adequate performance?

In this well-paced video from the "Ham Radio Concepts Amateur Radio Channel", we see some intriguing, inexpensive HF antennas that blend in with their surroundings and give decent performance.

Many of the antennas described in this video come from designs created by N9SAD.  Most of his stealth antennas are ultra-light and can be used in a variety of operating environments.

If you're living in a controlled housing area, this video can give you ways to get on the air without bothering your neighbors.

Ham Radio - A quarter wave groundplane antenna for your HT


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=ViodMxV77eM.

If you're dissatisfied with the antenna on your HT, why not make an efficient, inexpensive replacement for that "rubber duck" that came with your HT?

In our last post, we discussed how adding a "Tiger Tail" counterpoise wire could boost the performance of your HT. In this post from Kevin Loughin (KB9RLW), we can get some real improvement in coverage by using a simple quarter wave ground plane antenna with our HT.

Kevin does a good job of showing us how to make one of these easy, efficient antennas for the VHF/UHF amateur radio bands.

You may be surprised just how well your HT performs once you attach a decent antenna.

Increase HT Range & Performance Free Mod ( Baofeng UV)


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=N3R-b00pLbw.

Thanks to "connly33" for this simple, inexpensive way to boost the range and performance of a VHF/UHF HT.

The secret of  better performance is the use of a "Tiger Tail" or counterpoise wire attached to the base of the antenna input.  For the lower part of 2 meters, use a 20 inch/50.80 cm length of wire.  For the upper portion of 2 meters, use a 19 inch/48.26 cm piece of wire.

You may be able to build a small counterpoise wire with the materials in your "junk box."

Multiband & EFHW Antenna Presentation at BVRC


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=BpdpkUEW39o.

In this well-paced video, Steve Ellington (N4LQ) compares a variety of multiband HF antennas with the end-fed half wavelength antenna.  Steve does a good job of explaining the pros and cons of several popular antennas and explains why the end-fed half wavelength should be among your favorite antennas.

Other than a few minor quibbles about the relationship between baluns and antenna currents, I found the presentation factual, interesting, and useful for both newly licensed radio amateurs and the "seasoned", experienced operator.

Turn this 28m light pole into an antenna for 1.8 MHz. Post 2048.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=iGQJRhWViMI.

Here's another intriguing and somewhat strange antenna project from Australian ham Peter Parker (VK3YE).

Peter shows us how to convert free-standing light poles into workable vertical antennas for the 160 meter amateur radio band.  Please get permission from local authorities before you try this antenna.

Peter offers this commentary on this unusual antenna project:

"Ever thought about how good those light poles you see at sports ovals would be if only you could connect them up as an antenna? Wonder no more. With a coupling loop it's possible to load them up on at least the 160 metre amateur band. Video demonstrates how it's done with contacts made with 10 watts of AM on 1.8 MHz. The variable capacitor and coil used in series with the feed coil is the ground tuning unit described in a previous video. Recording by Clint VK3CSJ at https://www.youtube.com/watch?v=VO--I...

A new carbon-fibre mast from SOTABEAMS.
Source:  http://www.southgatearc.org/news/2019/november/lightweight-carbon-fibre-mast.htm#.XcR1aEtKjIU
Accessed on 07 November 2019, 2005 UTC, Post 2046.
Summary:

If you do a lot of portable or emergency radio operations, you may find this new product from SOTABEAMS a valuable addition to your amteur/ham radio "Go-Kit."

This compact, lightweight carbon-fibre mast is ideal for remote locations where an end-fed or inverted V antenna would be desirable.

Here's the formal announcement from SOTABEAMS:

"A class-leading lightweight carbon-fibre mast from SOTABEAMS

Portable specialist SOTABEAMS has launched a new carbon-fibre portable telescopic mast. The Carbon-6 has an extended length of 6 metres (19.6 ft) but weights just 300 grams (10.6 ounces). Its packed length is only 43 cm (17 inches) making it a mast that can be taken pretty much anywhere.
The Carbon-6 has been designed for light-duty operations and is best suited for supporting the centre of end-fed wire antenna in inverted vee fashion.

It is likely that this will be a popular choice for the portable operator who undertakes more "extreme" forms of travel or just wants to travel light!

Windom Antenna. Post 2045.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=5PbOfZYzCUE.

Another "classic" multiband HF antenna to consider is the "Windom Antenna", originally designed around 1922 by Loren G. Windom (ex-W8GZ).

Windom's original design was fed by a single wire connected on 1/3 of the antenna's total length, with modern versions using balanced line and coaxial cable to feed this off-center fed dipole.

Windom's design often created RFI and SWR problems because it had no "return conductor" or shied on the single feed wire.  Modern versions have largely solved the common mode and RFI problems found with this antenna.

In this video, Stan Gibilisco (W1GV) provides an excellent review of the theory, construction, and use of this nearly 100-year-old design.  If you build and test this antenna carefully, it will give you years of contacts at minimal cost.

Ham Radio - A 75/80 meter single band fan dipole. Post 2043.

https://www.youtube.com/watch?v=4qwQzVdRRec
If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=4qwQzVdRRec.

Thanks to Kevin Loughin (KB9RLW) and his friend Jim (AC9EZ) for this intriguing answer to large SWR swings found on dipoles trying to cover the entire 80 meter Amateur Radio band.

According to Kevin and Jim, a modified fan dipole with elements cut for both the 80 and 75 meter segments of the band will provide low SWR across the entire 75/80 meter band.  Using 450 ohm ladder line and a good antenna transmatch (i.e. "tuner") are keys to making this antenna attain maximum efficiency.  A good, simple antenna that will provide wide 80 meter coverage at a reasonable cost.

An Awesome Antenna For 2m SSB CW, Part 2 Test. Post 2042.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=VcU2BZ7aBB8.

Here's part 2 of the "Hourglass Antenna" from "Radiopreppers.com."  The antenna is based on a design by John Stanley (K4ERO) and can be used successfully on 2 meter Single Sideband and CW.

According to the "Radiopreppers.com" website, this horizontally polarized VHF antenna can also be used on VHF digital modes.  The antenna has approximately 5 dB gain (nearly as much as a 2 meter Moxon Antenna), is almost omni-directional, and is easily portable.  The antenna shows a 50 ohm impedance and can be fed with a good quality coaxial cable.

An Awesome Antenna For VHF 2m SSB CW, Part 1 Build. Post 2041.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=7fsFx_Wf2Ko.

This somewhat unusual "Hourglass" antenna from "Radiopreppers.com" is a horizontally polarized antenna for those involved with 2 meter SSB, CW, and digital modes.  The original idea for this antenna came from a "QST" article, which is cited in the links below.

In part one of this two-part series, we get a general overview of the theory, construction, tuning, and use of this antenna.

Here's the overall description of the antenna from "Radiopreppers.com":

"Its vertical shape makes it easy to fit anywhere and it is not too long to fit inside a regular car. Efficiency is near that of a Moxon, about 5db, but with a bi-directional, almost omni-directional pattern. Much bigger than a Moxon, which I consider to be portable, but nevertheless it could be dismantled for transport. It is sort of a double Delta Loop. The feed-point has a fifty Ohm impedance, which is another great advantage as no matching is required.

NVIS Overview (#231). Post 2040.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=s2iMoXLO0s4.

Here's another excellent presentation from Dave Casler (KE0OG).  In this video, Dave provides what he calls "a quick and dirty look at NVIS."

NVIS stands for Near Vertical Incident Skywave--a practical way to get excellent local, state, and regional HF coverage with low-mounted dipole antennas.  Recent events in fire-ravaged California are proving the worth of these limited range HF antennas, especially where wildfires have destroyed or rendered VHF/UHF repeaters inoperable.

Dave does a commendable job of explaining the theory, construction, and general operational parameters of NVIS antennas.  This video would make an excellent presentation to an amateur radio club or for an introductory amateur radio license class.

9A4ZZ COIL Antenna. Post 2038.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=WyYoHYr_1YE.

If you want to experiment with a HF helical coil antenna, then this short video from 9A4ZZ may prove interesting.

This antenna uses a large coil wrapped on PVC pipe.  The closely wound coil is tapped for the various HF bands of choice.  An inexpensive steel tape measure is used to form a simple  elevated counterpoise.

The antenna seems to work well, considering the losses involved.  You may be able to make this antenna using locally found parts and PVC pipe found at your local recycling center or neighborhood yard sale.

Bobtail Curtain Antenna. Post 2033.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=6dU2b0AHD1M.

Here's a great antenna for the ARRL Field Day.  Stan Gibilisco (W1GV) does a good job of explaining the theory, construction, and use of this bidirectional, monoband broadside array for the Amateur/Ham Radio HF bands.

This antenna is by no means a simple affair--you may need help in erecting this array.  You'll find the effort expended in making this antenna well worth your time.  I remember using a 10 meter Sterba Curtain several years ago at a local DX-pedition and found the performance excellent.  With HF propagation now favoring the lower HF bands (160-80-40 meters), you may find the classic "Sterba Curtain" a welcome addition to your antenna "farm."

#28: My QRP "go kit" backpack with IC-703+ ham radio


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=yIZVBKND_II.

Every radio amateur should have a "Go-Kit" for portable or emergency operations.

In this well-organized and easy to understand tutorial, W2AEW show us his personal "go-Kit" made from easily obtainable materials.

W2AEW explains how he assembled his portable QRP station:

"This video shows my portable ham radio station "go kit". It is contained in a backpack from PowerPort (http://www.powerportstore.com/). My lovely wife had the pack embroidered with my callsign before she gave it to me. She also bought me the ZM-2 tuner kit, as well as the AstroFlight Whattmeter (thanks to Jerry N2GJ for the suggestion!). It's wonderful having a supportive spouse! The antennas are the Par Electronics tri-band end-fed antenna, and the Super Antennas MP-1 multiband vertical antenna. The tuner is a z-match style tuner from Emtech. I use 7aH gel-cell batteries, and charge them with a Battery Tender float charger from Deltran"

Ham Radio via Bicycle Mobile on 6m with IC703. Post 2031.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=_tknnqTC-7A.

Bicycle mobile operations are becoming more popular these days, especially when deed-restricted properties and other impediments hinder Amateur/Ham Radio activities.

In this video, Steve (WG0AT) shows us his 6 meter bicycle mobile system and documents some of the ham stations he contacted along his bicycle trip.  According to Steve, he was surprised just how well his system worked:

"I was absolutely amazed how well a short whip antenna and QRP/5 watts work on 6m But the best part is working 6m from my bicycle! It's a real thrill to have stations come back to you and be able to tell 'em your QRP Icom 703 and to boot your on a bicycle (albeit at rest) using a Buddipole whip on your handlebars! How cool is that?"

Why not make a portable system like Steve's? Imagine riding and operating bicycle mobile as you travel to your ARRL Field Day site. Great, imaginative video from Steve!

5 Min Emergency Antenna. Post 2030.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=XgyH6JQ3XHo.

Here's a quick and easy way to make an emergency HF antenna for your ham station or for portable operations.

Jerry  H. Kolins (K2PFW) shows us how a convenient legth of coaxial cable and a few simple tools can get you on the air in just a few minutes.  As Jerry shows, the outer shield of the coax becomes the "other half" of a regular 1/4 wavelength dipole "oriented in the vertical direction."

I've seen this type of antenna often called a "sleeve dipole."

Why not make an emergency antenna for your favorite amateur/ham radio band and keep it in your "go-kit"?

How To Build A Nested Faraday Cage - Protect your Electronics From An EMP


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=jGJYvOPP9O0.

During the past few days, I've urged my fellow radio amateurs to protect their ham stations and other sensitive electronic equipment from power surges, RFI, and EMP (Electromagnetic Pulse).  EMP can come from a variety of natural and human-made sources.  EMP can damage your antennas and transceivers if you don't take steps to protect them. Fortunately, you can lessen the danger of EMP damage by building a "Faraday Cage".

In this well-paced and thoroughly detailed tutorial, "Reality Survival & Prepping" discuses how to build a nested Faraday Cage for your electronic equipment.

Here's a list of some materials needed for this project:

"This faraday cage is using a nested system with multiple different materials that should protect your electronics from a wide range of the electromagnetic pulse frequencies. Here is my video on 17 Misconceptions about EMP's: https://youtu.be/GARhAT0zLV0 Copper Mesh: http://amzn.to/2tfZb94 Aluminum Foil: http://amzn.to/2tgjWBf 3M Metallic Tape: http://amzn.to/2t51Rv3 Copper Tape: http://amzn.to/2tgc7vl Gallon Zip Lock Bags: http://amzn.to/2sS7kko Faraday Defense Bags: http://amzn.to/2ukppMq Behrens 10 Gallon Galvanized Steel Can: http://amzn.to/2sSpwdI Glad Press N Seal Wrap: http://amzn.to/2ug1ugm Quart Size Zip Lock Bags: http://amzn.to/2tgfqTk Support this channel by purchasing your gear through my Amazon link!

An inexpensive 3-Band Magnetic Loop Antenna


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=B-tYtbTts0s.

Here's another great antenna idea for radio amateurs living in deed-restricted homes or apartments.  Why not build a simple magnetic loop antenna for home or portable operations?

In this video, Dennis Blanchard (K1YPP) describes an easy method to build a simple magnetic loop antenna covering three popular HF bands (40/30/20 meters).

This clever, imaginative magnetic loop antenna can handle 100 watts input and costs around $20.00 USD.

Although magnetic loop antennas have some drawbacks, they will get you on the air at minimum cost.  Better a compromise antenna than no antenna at all.

Deploying an Off Center Fed Dipole Antenna for Ham Radio. Post 2026.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=D4P5DdvsLys.

If you're tired of your usual HF antenna, why not try a popular variant of the "classic dipole", such as the Off Center Fed Dipole?

In this well-constructed tutorial, Johnny (W5KV) does an excellent job of  explaining the general theory and construction of the OCF dipole as he shows us how he deploys a popular HF ham radio OCF antenna.

As you would expect, erecting the OCF may be a bit more complicated than installing the traditional horizontal 1/2 wavelength dipole.  With a little time and perhaps some help from a fellow ham, the job can be done without major problems.

How To Build A FARADAY Cage that actually works. Post 2025.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=EiNQbWZFe-E.

It's not a matter of "if" but one of "when" an EMP incident will sweep past our planet, potentially endangering your digital and solid state radio equipment.  Something akin to the 1859 Carrington Event could make life quite precarious for a world now overly dependent on digital devices.

In this video from "Survival Lilly", we learn how a surplus military ammunition case case can offer EMP protection for your small communication devices such as HTs, small VHF.UHF/HF transceivers, and even your credit cards and IDs.  If you're ambitious, you can make larger Faraday Cages from large metal trash receptacles or old kitchen appliances such as decommissioned stoves and refrigerators.

This video offers a variety of ways to protect your radio equipment from natural and human-caused EMP.

Ham Radio Grounding System & Lightning Suppression. Post 2024.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=mRrDQPdmxtc.

If you live in an area plagued by thunderstorms and lightning, you may find this video from KF7P ("Signal Search") helpful in designing a system to protect your amateur radio equipment.

KF7P shows us what he did to increase the survivability of his ham radio station.  It's best to be over prepared than under protected.

While my QTH doesn't experience the weather extremes experienced by KF7P, I do find a few thunderstorms often knock out our locally generated power when lightning strikes a utility pole in my neighborhood (Hawaii Island).  I've always made it a practice to detach and ground all antenna feed lines when I'm not on the air.

Kitchen Foil Hula Hoop Loop for 15 to 10 m. Post 2023.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=gQWbWWvGapw.

If you need a super-cheap, easy-to-make magnetic loop antenna, try this suggestion from Australian radio amateur Peter Parker (VK3YE).

All you need is an old "Hula Hoop" from a neighborhood garage sale, some coaxial cable, wire, and a willingness to experiment.  According to Peter, this homemade magnetic loop antenna works well between 21 and 30 MHz.

Put your recycling knowledge to good use and make this "bare-bones" HF antenna.

Ham Radio and EMP. Post 2022.


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=7PR2ExR7mX0.

In our last post, I briefly review an article on Extreme Solar Events which could impact your neighborhood, home, and amateur radio station.  If Coronal Mass Ejections (CME) are sufficiently powerful, massive parts of our communications infrastructure could be rendered unusable.

One of the unfortunate results of a "Carrington Event" would be EMP (Electromagnetic Pulse),which could produce serious damage to your home, including your ham radio station or any other solid state device.

In this video from Stan Gibilisco (W1GV) we get a good overall view of EMP, what it can do to our digital lives, and how we can mitigate some of the serious issues caused by EMP.

One of the easy ways to protect your radio equipment would be to store your transceivers (HF/VHF/UHF), "tuners", and electronic tools in a "Faraday Cage."

Here's an excellent article from "PC Magazine" that will help you design and build an effective "Faraday Cage" for your equipment:

pcmag.com/article/335782/how-to-make-your-own-faraday-cage.

Why not take steps to protect your equipment now before the next solar storm becomes an unpleasant reminder?

Protecting communications from the next Carrington Event


Protecting communications from the next Carrington Event. Post 2021.
Source:  https://www.universetoday.com/143677/power-grids-and-satellites-are-more-at-risk-from-extreme-solar-storms-than-we-thought/
Accessed on 14 October 2019, 0450 UTC, Post 2021.
Please click the above link to read the full story.

Summary:

Most radio amateurs have heard about the devastating effects of the 1859 Carrington Event which destroyed much of the world's rudimentary telegraph systems of that time. 

A renewed study of that solar event has painted a grim picture of what a similar event could do to our modern world, which is so dependent on sensitive digital devices.  Extreme solar storms and coronal mass ejections could  make many of our solid-state devices inoperable.  The threat to our health care and transportation infrastructure would be severe.

Scientists and researchers studying the Carrington Event believe similar solar outbursts occuring in 1872, 1909, 1921, and 1989 were almost as strong as the original 1859 disturbance.  In fact, the 1989 coronal mass ejection crippled part of Quebec, Canada's electric grid, leaving many of our northern neighbors without power for several hours.

In this article from "Universe Today", we get a renewed picture of what awaits us if we don't do something to "harden" and protect our power grid, communications infrastructure, and medical care systems.

According to this sobering article, there are a few ways to begin the protection phase of our digitally-connected society:

"There are a variety of ways to protect things like transmission lines form intense solar storms. Capacitor banks, Faraday cages, and special dampening devices could all help. But none of them are a perfect solution, and one 2017 study suggested it could cost up to $30 billion dollars just to protect the power-grid in the USA.

Some scientists have floated the idea of a massive magnetic shield between the Earth and the Sun. Sitting at the Earth-Sun LaGrange Point 1, the shield would offer the same type of protection that the Earth’s magnetic field already does, but more of it. But that’s just an idea at this point.
In the mean time, the best bet is to know when a storm is coming and to shut down the power system in hopes of minimizing the damage. Future missions like the ESA’s LaGrange Mission might help with that. As far as satellites and communication systems go, protecting them is a work in progress, and nobody seems to have an answer, yet."
---------------------------
How well is your ham station, your home, and neighborhood protected against future Carrington Events?  Do you have backup power?  Is your radio equipment protected? Do you have sufficient emergency supplies, including water, food, medical supplies, and sanitary disposal devices to survive the loss of power grids, internet services, and communications?
Something to think about.
