[QUOTE=&quot;FOX TV, post: 33175, member: 4493&quot;]In our market with most of the transmitters are located on top of a 4,000 foot mountain, when the wind gets up to around 60 MPH or better, I have actually seen or old top mounted analog antenna move as much a 1 foot off center. It is hard to believe that the wind could effect an 8,000 pound schedule 80 pipe that much, but I have seen it many times. That antenna is an Andrew UHF Slot antenna that is actually made from a section of schedule 80 pipe with slots machined in it for the inner conductor to radiate through the slots.When analog was still on the air, I could tell when the wind was blowing hard on top of the mountain because of the video and audio breakup. I think that some of the wind issues we see could be related to the Broadcast antenna being moved around by the wind. It is likely that wind blown tree foliage could be a culprit too, but that does not explain the issues I saw with analog in the winter when all of the trees were bare, and the breakups and bad analog audio were actually worse in the winter when the winds blow stronger on top of the mountain.Just my 2 cents worth on wind blown antennas and reception issues when the wind blows hard in this area.[/QUOTE]
