Hi Cecil...

Vote #3 for the coax feedthrough...sounds like this trick is well
known and escaped all my reading.

Thanks and 73

For that 6" run, just use two pieces of parallel
coax. The inside conductors are your balanced
conductors and the braids are grounded. Be sure
not to exceed the voltage rating of whatever coax
you choose to install.
