At the base, I see no signals except from my radios, with the spectrum analyzer.
I've still not been able to get the guy to climb the tower, in other forum's I've found people with horizontal antennas, having a problem on RX at the AP only with too much downtilt. Near the tower there are a few apartment complexes and hotels that are in the focus of the main beam at that downtilt. When I get the guy up on the tower, I am going to try uptilting it first for sure, maybe with that tilt they are picking up more noise then they should be.
