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

[Douglas Ruz (CO8DM)]

Thanks Ron,

Interesting idea using a solid hard wood shim a little larger than the base.

Bolts diameters are 3/8".

Bolts length are 2 1/2".

are not ok 4 bolts with that dimension to fix a base to the roof for 3 tower 
sections like Rohn 25G ?
