Hello TOP BANDERS
I see Cushcraft has a new 160m vertical
that is 30 -36 ft tall with 3 foot stinger on top
directly above coil with short capacity spokes -
given say 40 radials, as in PORTABLE operation -
with decent ground conductivity beneath - what are we talking
here - SINGLE digit radiation efficiency ? say 5%?? under
10 % efficiency ? Thirty six feet is about 0.067 wavelengths !!!
I feel fortunate to TAP into the rather LARGE BRAIN
TRUST of this reflector - which combines both theory
and " hands on " application !
