Re: [Elecraft] Need help from an EZNec user on a horizontal loop question

My current antenna is an Inverted L 1/2 wavelength long at 80 meters and is direct fed. That length puts the voltage "loop" (maximum) at the rig, so the counterpoise requirements are minimal on 80. The L is 40 feet vertical and 80 feed horizontal. That puts the current max near the bend on the "fla

Don, Good suggestion. Let me suggest a variant that at least two of use are using. I use it because of my severe space limitation. Basically, the antenna is an inverted L that is fed at its center at the top of the vertical run thereby obviating the need for a ground. It has a total length
