I don’t even update my DXCC totals anymore as it no longer represents an
accomplishment that I can share and enjoy with fellow operators
for 80M may be quite different than for other HF bands.

I meant to post this to the TowerTalk group. It still may be relevant to
Topband ops.

Very interesting and timely discussions on radials and ground conductivity.
I’m currently rebuilding an 80M broadside array (with shortened, top loaded
elements) in SW Utah that I’ve modeled at 12 ohms impedance. The current
antenna was tested and the impedance measured was 25 ohms. Each element in
Thanks for all who responded. I’ve taken the liberty of sharing my response
to Hank, K7HP who touched on many of the potential issues posted by others:

I have 4 identical short verticals (part of a broadside array) where EZNEC
predicts a 12.5 ohm feed-point impedance. That seems reasonable, but my
actual measurements indicate 25 ohms at resonance.
My first thought was something lossy in the ground system. The ground
system consists of 32 copper
