Hi Herb,

When I was in Durban as ZS5K, I was in a similar situation in that I could only 
run a Bev in one direction away from the shack.  What I did was to put a small 
relay at each end which switched to a termination in the unpowered state, and 
to a coax feed in the powered state.  I ran a coax from each end to the shack, 
where I had an antenna switch.  I inserted DC on to the coax, so that which 
ever one was switched in powered the correct relay.

Worked pretty well for me.

73, Greg, ZL3IX
