Hi Richards,

I will add the attached to my web site -- it probably won't get to the group. As you can see, I have 2x8' braces underneath the roof joists and use (2) 3/8" x 10" cap screws to sandwich the joists between the tower feet and the braces. If the antennas go, the roof will go with them... ")

73,

Nice images on your webpage, Larry.

Did the you have to reinforce the roof or trusses underneath
 before installing the roof towers?  Here in Michigan, we are
told to reinforce the underlying trusses -- not so much because
of the weight of the tower and antenna system, but because of
twisting and torque stress.


Thank you.
