160M Shunt Feed Tower 

I shunt feed my 100' of Rohn 45 using a three wire cage. Matching is performed  with this "Shunt-C/Series-C" matching system.  I use a remote motor driven vacuum variable capacitor. The matching system is enclosed in a black and clear waterproof Plexiglas enclosure with a control unit 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 provide more detail.
