[WISPA] TV interfering with 5.8GHz?

2009-10-29 Thread Adam Greene
Hi, Just installed a 5.8GHz Alvarion VL on a roof with lots of TV antennas. Interference was horrible. We were not expecting that, as the main TV antenna culprit says 490 on the side -- I assume 490MHz. My obscure reasoning tells me that if there were a really strong signal on 483.33MHz, it

Is the interference to you or to the TV signal? What is grounded and where? Perhaps you are causing a ground loop by doing grounding differently than they did or something? If to the TV signal ? Are you using shielded cat5e cabling and grounding an end of the shield drain wire? Any other

Guys, thanks for the brainstorm ideas. Interference is to us. And yes, it makes sense that since this is not a TV station building, these antennas are probably receive only. There is a huge omni antenna with 490 printed on the side, which is where we took the idea of 490MHz from, but it's
