How to get gain and directionality for your POTA vertical antenna.
We show you how to use the free EZNEC program to analyze antenna properties.
In this video we demonstrate how gain and directionally can be obtained for a simple vertical antenna by using a single elevated radial. This makes the counterpoise independent from ground conditions.
Here are links to previous videos about using ground as a counterpoise.

The electric fence posts shown in the video are available at TSC Tractor Supply Co., Rural King, Menards, and at any farm/ranch supply dealer.
* Near the end of the video I state that a gain of 3db is obtained. I misspoke. I should have said 2db as shown earlier in the video.
