[TVARC] K4QR’s Station Temporarily Off-the-Air Due to Buried Coax Failure

[Bob Easton]

Tony,

Are you certain it's not just one of the connectors, a far more likely 
failure scenario? Before you go to the expense / effort of digging up 
the cable. Do you have a way of testing it? It's pretty easy to test 
with a NanoVNA. I'm willing to help if you want.

73, Bob, N4REE
