Hi guys, currently working on getting a radial net worked into my garden &
pavement. Appr 40 radials ranging from 10 to 40+ meters.
I can raise vertical to appr 37 meters. main interest is 160 meters.
I would liketo use this vertical for 80, 60 and 40 meters. Considering
end-fed configuration for 8
Forget about the high impedance issues on 40 and also 80. IMHO the best
and easiest solution for you is to make some simple wire decoupling sleeves
or wire cage for the higher bands and they could be current fed like 160
meters and much less complicated to feed without extensive matching. Also

. Clearly, size matters.

Respectfully, there's a lot of misinformation here.
"Clearly, size matters." If you are saying that the taller a vertical then
the better the signal, then that is simply *not the case*. It is a very
well established fact that a 160m vertical taller than λ/4 has little --IF
ANY-- DX advantage. (Rat

The free-space pattern of current in a vertical (and also horizontal)
antenna is crescent shaped with its maximum at the midpoint, and a minimum
at each end. It shows nothing that could be termed an extraneous lobe. Any
Here's some interesting comparisons of the patterns of 1/4λ vs. 5/8λ mobile
antennas.
