[TowerTalk] Phillystran vibration damping?

[donovanf at starpower.net]

Hi Dick,

I was very concerned that the vibration would damage my 
towers, so I took no chances.   The Preformed Line Products 
SVD dampeners completely solved the problem by installing 
one dampener at the top of each guy, within reach of the tower.

As the PLP literature describes, some cases may require more 
extreme measures involving multiple SVDs, but one per guy 
was adequate in my case.

73!
