[BC] Wind and STL Mutes

During a recent blizzard with high winds my STL (Mosely Starlink) for one of my FM's began muting.  This problem first reared its ugly head last March and after much discussing with Mosely a 10 watt PA was installed and the problem disappeared until last night  The RX is installed at a fairly hostile tower site, beepers, 2 cellular companies, etc. installed on three different towers.

My guess is there's something loose somewhere on the three towers and when the wind blows the loose connection is arcing and muting the STL..  Rather than me going to the Manager and telling him that we are going to have to have every nut / bolt / coax connection checked on all three towers including the chain link fence, does someone have some advice which could narrow this search down a bit, or possibly other causes for this behavior.  The link has no troubles other than this.

Transmitter output is 10W  950 Mhz digital, a bandpass filter is install, and the path is only 6 miles or so,  this should be a very robust path and yet here I am.  I know I have seen a thread on this here before but can't seem to find it now.

Thanks All,

Carl
