Do you have a way to test your coax runs? Maybe critters have eaten part of a cable. I found this in my rcv array field where I have a huge Vole issue.

Whats a good way to test and troubleshoot a 2 element phased array? I have a 2 element array on 40, using the Christman feed method, which used to work quite well.....something doesn’t seem right with it now....the one direction, maybe is ok, but doesn’t seem to have the gain it had before.....but the other direction, signals are way down, even signals that should peak when switched to that direction.....I have a rf ammeter, can I used that on the feedlines to try to determine where the problem is?

Do the two elements have the expected performance by themselves? If you A/B them against the same signal, do you get the same strength?
