Check Electronix.com or MCM. I bought one from one of those. It's called an
isolator.

Can anyone help locate a part or part# for cable input coupler?

It has a male RCA connector on one end and a female "F" connector
for a coax input.

Or the part may be the whole subassembly with a coax and twinlead
teminal.
