Subject: [TowerTalk] DXE 8 element Circle array problem

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?
