I smile at the responses you have received on your plans for the  KT34A.    I 
smile as I agree with most of them.     The HD73 is the poorest of all rotors 
for amateur radio.   Has one  poor braking system.   In fact hardly any.  
(BTW you can  find a HAM-M rotor or Ham II for less than $150 and they won't 
windmill like the  HD73).   The mast idea is not a good idea.    Check out  the 
windload on that beam and my bet is that you will not want to use a simple  
mast.
 
The beam should not be mounted more than a foot above the support structure  
as others have said.    And don't kid yourself, a mast fastened  to the side 
of your house could probably rip the side of our house  off.   It's happened!   
 In fact many communities  won't even let you mount a mast to the side of the 
house any longer.
 
My suggestion is to use  nothing smaller than a roof tower  or  Rohn 25 
others have suggested.    But better than that  get a real tower!    A Rohn 
HDBX or 
a Universal or
US Tower.    Wait a little longer and save the bucks that's  needed to do it 
right.    You don't 
want your beam and mast (you have suggested) to fall on your kids, neighbor  
or you!   You can usually find one used if you look a little  longer!
 
Good luck.    Do it right and you won't be sorry  Scott!
