I have two #10-24 stainless threaded rods going through the concrete block
wall in my shack near the ceiling. They are insulated on both sides of the
wall with ceramic insulators. I use the manual version of TT's 2KW tuner
and run 450 ohm ladderline from the balanced output from the tuner straight
up to the feed-thru's and on the outside of the wall I continue the same 450
ohm stuff to whatever antenna I am playing with at the time. I got one of
those dual knife switches from The Wireman, and mounted it on the wall just
below the feed-thru's so I can disconnect when we get our usual
thunderstorms here in South Florida.
I mostly use it for a full-size 80m loop fed in the lower corner.
[Triangular delta-loop Apex up at 60ft near the top of the tower with a
tribander on top and a 40m rotating dipole 10 ft above that] That antenna is
a monster on 75 and 80. Nab the DX usually 1st or 2nd call. Can tune for
any band except 160m, so for 160m I put a SPST n.c. relay to open the loop
at the mid-point. Then it becomes a folded diploe and will load ok using
the tuner. I admit it's a very compromised antenna for top band, but works.
Not bad for limited real estate one-tower setup.
