[TowerTalk] More friction needed

[David Gilbert]

Personally, I think the idea of using multiple U-bolts is the best way 
to go.  As Rick says, the K7NV design doesn't really offer much 
additional surface area if the mast isn't perfect.  I welded a piece of 
channel iron perpendicular to a plate and drilled holes for eight 
U-bolts in the channel iron.  It holds great in spite of twister winds 
that reach 80 - 100 mph here in the spring and when they hit the tower 
head on the torque from the twister combines.

I stole the design from a commercially available unit, but I can't find 
the source for it anymore.
