[TowerTalk] Guying Alum Tower

[Bryan Swadener]

Another factor is liability. When I consulted my insurance agent, 
I was told liability for my tower would be covered if all zoning 
and permitting requirements were met. In this case, I very much 
doubt a homeowner's modifications would be covered unless it was 
determined by a structural engineer that it was safe.
