[TowerTalk] Fwd: how to install the tower base over a sloping roof???

[John Bohnovic]

Remember that he is in a hurricane prone area. He is south of the 
Florida Keys and I believe the Keys have a 115 mph, or greater, wind 
speed factor. I saw what happened to channel six's tower, which was 
located near Homestead, FL when hurricane Andrew ripped south Florida apart.

If you plan to remove the tower at some time in the future I suggest you spread out the cement over a single plastic sheet at the spot where you are putting the tower. That way you are able to remove the cement without leaving any marks.
