Well I'm using BulletHP's, but I have them on other towers, and they work fine. I have the Ubiquity 3.4 firmware on them, it's not the radio's, not the antenna's, it's definitely something with this tower configuration. The only thing we did differently is use RFlinx Lightning arrestors inline, but I don't see how they would affect only receive and not transmit, it has to be the configuration of the antenna's on the tower. As has been suggested I think it has to do with them being to close together, they are too hot, and even though the channels are non-overlapping on the 3 AP's, the attenuated portion is still too strong and messing up the RSL's badly on the AP's.
