I shunt feed my 100' of Rohn 45 using a three wire cage. Matching is
performed with this "Shunt-C/Series-C" matching
use a remote motor driven vacuum variable capacitor. The matching
enclosed in a black and clear waterproof Plexiglas enclosure with a
in the shack with a digital readout . I have a variable 45 KHZ segment
with a 2:1 bandwidth, selectable by the control unit.The pictures below
