Dave, K4SV asked:
"Wanted to ask if the normal calculation for a 1/4 vertical applies
(234/F(mhz) = Feet of antenna for 160 meters using a Rohn 25G section of
tower for the radiator (125 foot)?"
==========
13 sections of Rohn 25G is 126' 6" and will be resonant at 1845 kHz over
a good ground radial system per my EZNEC tower models. A 3-foot
"stinger" on top of that will bring it down to 1830 kHz.
