Dale,

I made a bet that this thread would revert to a house bracket tower wind load question.

Its not really the people fault that only read the Rohn manual and never have climbed a tower.  
They don't understand how nervous the company bean counters get when someone sues them.  
The wind blows and someone gets sued.
That they don't have Rohn specs dated 25 years ago that spec 25 like 45 is specked today.

As far as 'them' telling me I should be 'worrying' about adding a extra 6 sq. ft of wind load, I don't.

Why, you ask?

The 3el 40m was so heavy when we tramed the antenna up it bent the DOM mast! What did we do?
Replace the tower?  Replace the mast pole?

Nope, we rotated the mast, hooked the truck back up to the pole and pulled it back straight!  

I GUARANTEE YOU that we put more stress on that tower that ANY hurricane wind could.

So yes Dale I think you had a great set-up and like yours, mine don't creek, move or sway.

Take care and
73,
Lee

Lee: I had an 80' Rohn 25 tower with two house brackets bolted into a 40' high chimney with NO guy wires it was up for 30 years in an area that sometimes gets pretty strong wind gusts here in Atlanta. It never even vibrated.  I swear to you that in 30 years we never had to climb the tower once-- not for the 4 el tribander; not for the rotor (never ever lubricated); not for the coax or connectors. Maybe just lucky???
