Re: [TowerTalk] Wind noise

[David Gilbert <ab7echo@gmail.com>]

If it is the tower that is vibrating, he could probably dampen it by 
putting tension on it with a length of rubber hose (or some other 
similarly mechanically lossy material).  His tower is bracketed to the 
house, so a hose fixed to the tower near the top and running to 
somewhere else on the house should significantly help.
