My Ham Radio Antenna Set Up And A Tour Of My Attic

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=Y-SgA_qno9A.  This is post 2189 in a continuing series of simple Ham Radio Antennas.

If you live in a deed-restricted home/apartment and have access to an attic, then getting on the air with modified antennas becomes a real possibility.

In this video from "Road Rage 810", we see how one radio amateur solved the "no antennas allowed" issue with a little creativity and imagination.

In this case, the radio amateur was able to install an Alpha Delta DX-CC HF antenna and a N9TAX 2m/70cm in his attic with only a few modifications.  Any antenna is better than no antenna.

How to set up a home-based Field Day station.

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=MeumSDLXBKM.  This is post 2188 in a continuing series of simple ham radio antennas.

The annual ARRL Field Day Emergency Communications Exercise is set for the last full weekend in June.  Depending on the outcome of the 2020 COVID-19 pandemic, you may not be able to join your club or your friends in the "field" this year.  Why not operate (class 1D or 1E) from your home this year?

In this video, Tracy of "Outdoors On The Air" shows us how he prepared for a home Field Day station a few years ago.  You could do the same and still enjoy the long distance friendships and competition that this annual event brings without exposing yourself to a viral infection.  Here are some of Tracy's comments:

"Can't get out into the "real field" for ham radio Field Day? Maybe you should mount an expedition into your backyard. I'll show how I used to do it. I hope this is an encouragement to those who cannot get out to the field for themselves, but still want a taste of the experience. I ended up with a total of 135 contacts across 40, 20 and 15 meters. Footage was shot in 2014. As always, feel free to leave your comments below."

HyEndFed Field Day Antenna

If you can't see the video, please insert this title URL into your browser's search box:  https://www.youtube.com/watch?v=JuCSdAr1yDo.  This is post 2184 in a continuing series of simple ham radio antennas.

Barring any unforeseen circumstances, the ARRL Field Day remains set for the last full weekend in June.  It's not too early to be thinking about the transceiver and antenna you'll deploy that weekend.

In this video from "Outdoors On The Air", we get a good look at a fairly new end-fed HF antenna from The HyEnd Company. The antenna is compact, lightweight, and covers 80 meters through 10 meters.

Here's a brief review of this antenna:

"The HyEnd Company have released a new antenna, the Field Day 8-band Antenna. This 80-10 meter endfed was designed for portable ham radio operations. Let's take a look at the antenna, then watch as I utilize it in the 2019 ARRL Field Day Contest.

Ideas for compact 80m/160m antenna DX

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=th9bPEm9i9k&list=PUEWRZEIjVQB8aUkyUQ-g-zA&index=63.  This is post 2183 in a continuing series of simple ham radio antennas.

If you're having a difficult time getting an 80 meter or 160 meter antenna to fit the limited space of your property, then this video from Callum (M0MCX) may help solve your problem.

Callum explores a number of possible solutions, ranging from linear loading an inverted L to more complex answers involving coils, segmented dipoles, and even loop antennas.

Here are some of Callum's notes:

"Inverted Ls do work for these low bands but what if you don't even have that amount of space? Perhaps linear loading an inverted L might do the trick, although the bandwidth might be tight - and the impedance might not be perfect either. Anyway, we'll see. HEY! Subscribe here: https://goo.gl/thM5Vq My Shop: https://www.m0mcx.co.uk/store/products/ Enjoy your science folks. Good luck. Callum. M0MCX. DX Commander Founder."

Hom(e)brew open wire feeder

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=-d3g957EaQ8.  This post 2181 in a continuing series of simple ham radio antennas.

Thanks to George Donaldson (EI7KO) for this simple, inexpensive method of making open wire feeders for HF antennas.  The main problem with do it yourself (DIY) balanced feed lines is getting a sufficient number of wire spreaders for the feed line.  George has come up with some good ideas in this regard.

Balanced feeders are great for feeding loop and dipole antennas.  With a balanced "tuner", it's possible for a HF dipole to cover several Amateur/Ham Radio bands.

For another interesting open wire feeder design, please check out the March 2020 "QST", pp. 30-33.  Robert J. Zavrel, Jr. (W7SX) shows you another method of making open wire line for your antenna.

A Timber Antenna Mast

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=tWq4tgLH-yI.  This is post 2180 in a continuing series of simple ham radio antennas.

Thanks to Australian radio amateur Peter Parker (VK3YE) for this simple antenna mast project.  Rather than using metal or PVC pipe for his HF antenna mast, Peter finds pine wood a good substitute for more expensive mast materials.

The original mast was 6 meters (19.68 feet) long with a 2 meter (6.56 feet) top section added later.

Here's how Peter describes his mast:

"Timber mast suitable for supporting lightweight wire antennas. The mast is 6 metres tall plus a 2 metre top extension. It tilts over for easy work on antennas. The antenna supports dipoles for 40, 20 and 10 metres, coming off the one feedpoint. 15 metre operation is provided by the 40m dipole. 80 metres is covered by adding loading coils to the 40 metre dipole. The antenna is similar to VK5AH's dipole except there is a dipole for 10 metres instead of 15 metres. VK5AH: http://users.picknowl.com.au/~wavetel... Being timber the mast is suitable as the centre support for open wire-fed dipoles such as the G5RV. Though it has the disadvantage of requiring an antenna coupler, the single G5RV wire is lighter and cleaner looking as one wire replaces three while covering more bands. Since the video was taken the mast has been extended to 9 metres, with a 38mm timber dowel u-bolted to the top portion. To lower wind resistance and make the higher mast less obtrusive at the top the chopping board pictured has been replaced with a much slimmer PVC T-piece. Main items required (from timber/hardware store): * 45 x 90mm treated pine (6m lengths are good) * pole for top extension (and u-bolts for it) * Paint * A few big bolts with nuts & washers * Cement * Cable clips and mounting hardware"

Portable Power for 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=f8-jxMtpklw&app=desktop.  This is post 2179 in a continuing series of simple ham radio antennas.

Thanks to Michael Martens (KB9VBR) for this informative review of portable power options for your ham radio station.  Although this video only suggests antenna and power options for portable and emergency radio operations, it would be a good idea to consider what Michael is saying in our unsettled world.

Please take an inventory of your home and shack  supplies to see if you and your family have sufficient resources to survive if you are cut off from stores and neighbors.  At the very least, you'll get an indication of what you need before panic buying begins.

Here are some of Michael's ideas:

"My recent video on my portable HF transceiver kit generated a lot of questions on what I use for a power supply. So as I’m prepping for an upcoming camping trip, I thought I’d take a moment and share what I use for portable power when off in the field.

Which is better: Vertical or Dipole (#106).

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=pRTo01Qttbc.  This is post 2176 in a continuing series of simple ham radio antennas.

Thanks to Dave Casler (KE0OG) for tackling the controversial question of the better antenna--verticals or dipoles.

The short answer is "it all depends"...

"Vertical or dipole? Which is better for you? Antenna modeling software (EZNEC+) helps answer the question!"

Dave does a good job of laying out the pros and cons of each antenna design. Your choice will depend on many environmental, material, and permitting factors. About all you can do is experiment to see which design works best for you. As for myself, I use several antenna types, including dipoles, verticals, and loops. All work well for specific applications. Your results will vary.

Dave's explanations are clear, concise, and "right on the money."

Near Vertical Incident Sky Wave Propagation NVIS Antennas

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=fvZ7z-6wAy0.  This is post 2175 in a continuing series of simple ham radio antennas.

Michael Martens (KB9VBR) takes us through the theory, design, construction, and testing of NVIS (near vertical skywave) antennas.

These "cloudwarmer" HF antennas are perfect for state and regional communications, with signals reaching between 100 and 300 miles (162 to 486 km). 

As Michael explains, NVIS antennas are easy to make and can fill in communications gaps not covered by VHF/UHF repeaters:
"
Near Vertical Incidence Skywave Propagation is an effective form of HF communication for stations in a 100 - 300 mile range. Ideal for Emcomm, the emergency communicator should be familiar with the use of NVIS antennas and propagation.

How to Build a Six Meter Ham Radio Dipole Antenna.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=4K5Vj6wtpE0.  This is post 2174 is a continuing series of simple ham radio antennas.

Thanks to Randy Hall (K7AGE) for this excellent tutorial on how to design, build, test, and operate a simple Six Meter Dipole Antenna.

Some radio amateurs call the 6 Meter Band the "Magic Band" for its unusual HF and VHF characteristics.  When the band is open, you'll experience some interesting DX contacts--all with a simple, inexpensive antenna that can be made with locally available parts.

Randy describes the antenna this way:

"This video I show you how to build a 6 meter ham radio dipole antenna. This is another video to help you get on six meter. In this video I explain the half wave dipole antenna and show as an example the dipole that I built. A half wave dipole is one of the simplest antennas that you can build. The dipole is usually two pieces of wire, attached to a center insulator. The dipole is fed with coax, with the center conductor going to one wire and the shield going to the other wire. The formula to calculate the length of the antenna is Length in feet = 468/ Freq in MHz. So for six meter with 50.125 as the target frequency this works out to 9.34 feet or 4.67 for each of the two wires. Here is a link to a dipole calculator http://www.kwarc.org/ant-calc.html I build my dipole using ½ aluminum tubing attached to a center insulator that I build out of a piece of Plexiglas scrap that I picked up for free from a window glass store. I added various nuts, bolts, and u-bolts to make up the center insulator. You could also make the dipole by inserting some number 12 or 14 wire inside ½ inch pvc tubing. Or, hang the wire dipole from a tree. When you build the dipole cut your tubing or wire long, then trim to length by using an SWR meter or antenna analyzer. I use my MFJ antenna analyzer to help me tune my dipole. I also show my Elk Antennas dual band beam that mounts on the top of the mast. You can learn more about Elk at http://www.elkantennas.com/ I hope this is enough information to help you put together a simple antenna to give six meters a try. Randy"
