1. Topband: K2AV radiator vertical height.... (score: 1): Author: Peter Bertini <radioconnection@gmail.com>; Date: Thu, 4 Apr 2019 11:15:55 -0400; 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; /archives//html/Topband/2019-04/msg00001.html (6,837 bytes)

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.

(score: 1): Author: Peter Bertini <radioconnection@gmail.com>; Date: Fri, 5 Apr 2019 13:16:53 -0400; 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; /archives//html/Topband/2019-04/msg00003.html (6,907 bytes)

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; /archives//html/Topband/2019-04/msg00004.html (8,373 bytes)
