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." ----------------------- Thanks for joining us today.

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

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

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

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 you

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"?

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=U0WB-3UToLg. Here's another excellent video tutorial from David Casler (KE0OG).  In this video, Dave discusses a wide variety of Amateur/Ham Radio HF antennas from simple dipoles to complex gain antennas. Dave explains complex antenna theory and operation in an easy-to-understand, informal style, which makes this video suitable for both newly licensed hams as well as experienced radio amateurs. This video would make an excellent presentation for your radio club or for an upcoming licensing class.  Nicely done presentation!

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

Image
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 frequenci

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.
