Re: Topband: Quarter wave sloper ?

[Gene Smar via Topband <topband@contesting.com>]

I don't have a choke on the sloper feedline, but I did run the coax inside the 
Trylon tower legs into a steel box at the base where the antenna switch is. I'd 
often thought about shortening the wire for 60M and installing a loading coil 
and shorting relay at the coax/wire junction for 80M operation, but haven't 
convinced myself to go through the trouble.

Is a CM choke required at the feedpoint ?
If  I can't fit the entire required length of wire,(I think I can get aprx
110-120')  can I insert a small coil at the feedpoint ?  Perhaps relay
switched, to obtain 2 x segments.
I'm toying with the idea of using the 75m rotary dipole at the top of the
mast as a possible RX ant for 160m....might be worth a try at least. The CM
choke at the 75m rotary dipole has 10.5 k Z on 160m.  I have zero room for
dedicated 160m RX ants. My corner lot is only 89' wide x 115' deep.
