Why don't you put a 2 antenna switch box near the top of the tower and run
one coax down and to the shack. You can even put the DC down the coax to
switch the relay box if you don't want to run a DC line to the shack. I am
putting one of these at the top of my tower to switch between the HF beam
and a 6m beam.
