Collin,
I’ve got RG-214 coming out of my ears, but could REALLY use a piece of RG-142B/U (or a similar RG-58-sized double or quad shielded 50 ohm coax). I need about 18 inches or so. BTW… I’ve got these duplexers licked. I think the system is ready!

I made a new harness for my duplexer and think I have a little piece left over.

That takes away a lot of paths for leakage to bypass your duplexer. And I would add to the rule of thumb that the cable MUST be *silver* plated braid, which much or most of RG214 brands and probably all of RG142 is composed of. Or, my favorite is 1/4" Superflex, solid copper shiel d. Laryn K8TVZ [Image Removed] [Image Removed]
