[TowerTalk] Can?t add egg insulator...

[Herbert Schoenbohm]

I thought that you could safely put 30 feet of Rohn 25 un guy above a 
good house or side building bracket.  That is what I use here for an 
10/12/ and six meter tower but to get to 60' I have a set of Phillystran 
guys at the rotor plate.  The house bracket is in to 2X6 and they are 
back by a long 1 X4 .of treated lumber with over sized washers and nuts.
