RE: [Repeater-Builder] WEATHER RELATED STATIC

Another thing to keep in mind is what type of support is it? I remember many years ago noise bursts would show up soon after rain when we had a bit of wind on a local VHF repeater, it ended up as the used connector they had installed on the 7/8th and of course on the top side. This is in FL where wind induced static is very uncomon, we get the real stuff in the way of lighting every summer day.
 
In another instance in the NE we had static show up when it got windy. While we were painting the tower and someone was talking on the machine it got really bad, bingo...the tower sections had a bit of corrosion building up between them and the bolts needed a bit of torquing. The corrosion in the legs was acting as a diode and with movement it behaved as a spark gap transmitter and just as wide!  It was 50ft of 45G freestanding on a 2400ft Mtn so disassembly and cleanup was a simple club project. Ever since then I have used No-Ox on all of my tower sections during installation. 
 
If it's a really bad case and you do find the problem to be the tower sections pieces of braded strap between each section with a good solid connection may help.

DESCRIBE THE STATIC......
 
Maybe static is the wrong word....... Its more like loss of signal, like mobiles becoming HT's and HT's without antennas!
 
Like the receiver wants to hide ....... (Hi, Hi)
 
My only concern about wind vibration is that the antenna hasn't been played with.  We have windy days, but it's much worst during weather outbreaks! No where near as bad as just a windy day.
 

Thanks all!
