Short (1.5 ft) BNC cables connect a radio to an antenna. The first row is for the radios, the second for the antennas. Easy to get to, but mostly out of the way: I ended up with this, two rows of BNC bulkhead adapters, mounted on a 1/4" thick plywood panel, which is attached under part of the shack desk. It would be complicated, quickly get expensive, and not provide much isolation between antennas/radios. I considered (but quickly shelved) something using a matrix of switches or relays. But how to switch multiple antennas and radio? I wanted something more flexible than the basic N position switch, which is great if you want to switch several antennas on one radio (or one antenna between several radios). I finally built something I have been wanting for a while - an easy way to switch antennas and radio.
