[TowerTalk] 25G on the Roof

[Jim Smith]

Hi Wilson,

As K8RI points out, overturning moment isn't a consideration for a guyed 
tower.

It's a flat roof with 2x12 joists so ought to be able to take quite a 
bit of downward force.  Still "ought to" doesn't cut it when dealing 
with towers.  This is one of the (many) aspects the PE will have to 
consider.
