Yes, it would be great to have all four antennas up and ready to go. But until then your reply does not answer the question. I'm in the same boat. Two of the four 80m verticals are up and functional
I did not detail my situation at all, sorry. And, I do understand not needing to terminate the unused port on a remote coax switch. In my case, I am building an 80m 4 SQ TX antenna system. I have a C
