[TowerTalk] Unguyed, with house bracket?..warning

[Robert G. Strickland]

I used two 1in by 6ft threaded steel rods and ran them through about four 
rafters, bolting on both sides at each rafter - a chore. On the outside, I 
bolted a three inch steel 'L' that is about 1/4in thick and about two feet 
long. I ran this through the Rohn 25 and used four stainless U-bolts to 
connect tower to steel - and thus to the two steel rods. This installation 
is at the 30ft peak of my two story wood frame house - circa 1930. The 
tower goes up another 30ft to 60ft total. I used phillistran to guy it at 
50ft. It has been in place 15 years without incident. I climb it regularly 
to play around with wire antennas beneath the tribander on top. The whole 
installation is very stable. IMHO, anything less than something of this 
sort is not really "bracketed to the house." While not a real testing 
method, one should be able to climb to the top of any tower without any 
noticeable sway/motion; one should feel as if attached to something 
completely solid. The fact that it is a tower - of any sort - should be 
completely incidental in the mind of the climber/owner.
