ZL3XDJ 20m elevated vertical antenna vs 3 ele parasitic vertical.


 According to Brian (ZL3XDJ), an easy way to boost performance of your 20 meter vertical antenna is to simply elevate the structure off the ground and use only 4 radial wires.

Brian tested this arrangement against his 3 element parasitic vertical antenna with 300 ground radials.  He found the elevated vertical had a definite edge over his parasitic vertical system.

Responding reader "petemillis4666" found a DX improvement over his usual vertical when he elevated his 20 meter vertical antenna approximately 2 meters (6.56 ft) above ground.

I've had similar result when I raised my 20 meter vertical several meters above ground.  Apparently, raising the antenna above ground cuts antenna losses and lowers the radiation angle-a nice advantage for DX chasing.

Here are some comments from Brian (ZL3XDJ)"

which is better, my old 3 ele parasitic vertical antenna with 300 radials, or my new 1 ele elevated antenna, with only 4 radials. What a surprise i got testing these ants, and some results not found here, which are not in the handbook. Thanks to the station master/xyl/ wife , for her encouragement for more ants equals more enjoyment.

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.

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.

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.
