Ground Radials for Vertical Antennas

Thanks to N0KTZ for this excellent introduction to the theory and practice of making radials for vertical antennas.  A good ground radial or counterpoise system is necessary for your vertical antenna to operate at maximum efficiency.  Well-done, easily understood tutorial.

Here are some general comments from N0KTZ:

"Make your vertical antennas more efficient by making ground radials the appropriate length. I use an easy wire jig for sizing and tuning one set of 15 radials to work for 20, 40 (and ~80) meter ham bands. IMO: The best is to have separate sets of radials cut to a 1/4 wavelength. I’m building all of my portable vertical HF antennas as Quick Deployment/MULTI-BAND use for Parks On The Air activations, remote camping, field day setups, HOA antenna restrictions and emergency radio communications. ------------------------- ☕️ Wanna say thanks and get special recognition on my next video? --- Send me a dollar: https://www.paypal.me/n0ktz 🛎 Subscribe and smack the ding dong! ------------------------- “…the typical quarter-wave vertical is NOT an end-fed antenna - it's a center-fed antenna. The high current is right there at the feed-point. It is the center of a dipole that goes one quarter-wave vertically and the other half of the dipole which is made up of the ground and/or ground radials” --Kurt N. Sterba (May, 1993, page 71 -WorldRadio).

G5RV Multi Band HF Dipole Antenna. Post #1555.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aeNHIQ_j4Dk This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  Bernie does an excellent job of  explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV).  Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use.  The G5RV is an excellent choice for the 20 meter band.  Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.

Antenna for Condo Backyard-Stealth. Post #1542.

Don't let deed-restricted properties (HOA/CC&R) stop you from enjoying Amateur Radio.  In this video from AC2RJ, we see how some well-placed trees, a camera tripod, a telescoping fiberglass mast, and a "V" antenna can get you on the air without a lot of effort.  Add an antenna "tuner", a sturdy rig, such as the Yaesu FT-817, a microphone/cw key, and a simple grounding system, and you have a fully functional, nearly invisible ham station in your backyard.

Amateur Radio Bicycle Mobile Setup. Post #1554.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=2zWb-KnkGdY. Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise.  Why not equip your bicycle for 2 meter/70 cm mobile operation? In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station.  The project is straight forward, simple, and gives you emergency communications while you peddle down the road.
