Bug infestation in the relays? I had some ants that decided to make their home
in mine.

My array is not working in the NE/SW directions.
I found one of my cables had been chewed on by voles. I replaced it.
No change.
I checked all the cable to make sure that the center had not pulled back.
I have voltage on all four antennas. two show about 4.5 VDC and 2 show
about 1.4VDC. I believe this is what I should see as I checked other
directions and saw similar voltage readings.
I did find some braid that was inside one of the connectors that could
have been shorting out that element. No change when fixed.
I suspect that I have one or more bad active antenna units.
I have not taken the main array cover off in the field nor have I taken
any of the active antenna units apart.
I suppose the best way to check each antenna element would be to hook
each one up individually and make sure that they can receive a local
broadcast station and the levels are similar.
Am I on the right track here or have I missed something more obvious?
