Thanks for the advice. I've your 2 loop design in use for about a 
month now and it works well. Its just a foot or so above ground, but 
not very good ground.

I'm very impressed with your means for passing the 3 switching 
signals down the coax - very innovative. Have you ever come up with a 
scheme where you can power up a pre-amp as well as provide the 
switching signals down the same coax?

Thanks
