Hi All, I think we finally have this all figured out. Now I just have to figure out how to fix it. We've been up there for over 6 years now. It's certainly been a problematic site though. Constant channel changes (we have 3 competitors a mile away and pick up hundreds of ap's from in town)

We also colocate with an FM transmitter. Only 1300W though. we also had interference on our Ethernet lines. We solved it by moving radios away from the FM antenna (3 feet or so on a 90' tower) We also installed ferrits which helped (I actually used a conduit pipe). Grounding the cat5 helped too.

It also sounds like there is a new leak in the waveguide. One more thing you might try is to move the cable from leg to leg on the tower so that you variable length sections that do not resonate at 350MHz or ~100MHz (FM transminssion). On Wed, Jan 7, 2009 at 11:16 AM, Adam Goodman
