Here's one for you guys.  I'm putting up a Rohn 25 at the house.  
Attaching at 28 feet up with a bracket and another few sections 
to top out at 60 feet.

Would there be a advantage to using a thick (1 to 1.5 inch) piece 
of rubber to separate the house from the bracket?
Reinforced, hard rubber like several layers of fire hose.  
My concern of course is noise. 

I would be using bolts and washers for the connection and 
bonding at least 4 rafters together with 2x4's and 2x8's.

Also thought about neoprene washers like what is used in 
4X4 truck bodies.

Has anyone had experience CORRECTING a noise problem? 
I will spin a Mosley CL-36 with a Yaesu 450. The rotor is a tad bit 
under rated but wont be moving it much.  Yaesu says 10 
and Mosley is a 11 for wind load.  
Also K factor is 100 for rotor / 120 for antenna.
Again, not going to be spinning this thing like a top.

A opinions welcomed. 

Thanks and 73
