- My K2AV counterpoise is 12 feet off ground, which leaves me with a vertical run of about 45 feet for the vertical portion of the inverted L. I've noticed that the walnut tree I am using for a support

- 65 of vertical run for the inverted L. My question is how much would this gain for DX contacts? Pete W1BR (ex k1zjh) _________________ The radiation resistance would double from 4 to 8 ohms. The cou

- 4 to 8 ohms seems to be rather low for an inverted L... that seems to be more in line for a short vertical? I measured closer to 26 ohms using my analyzer at resonance. I'd expect some improvement in

- Pete 1. If 26 ohms is the driving impedance including ground loss, you may simply have a lot of ground resistance. If it is the true driving impedance less ground loss, see #2. 2. 4 to 8 ohms is the
