I wouldn't use a 6' mast above that little HD-73. The 
rotator can't handle it. Mount the beam immediately above 
the rotator.

If you put the rotator and beam right above the top house 
bracket, you can probably get away with a cheesy mast, such 
as chain link fence top rail. You could probably go 8 feet 
above the house bracket with a fairly substantial mast, such 
as 2" x 0.125" wall high carbon steel tubing, but you won't 
be able to find a piece 26' long.

You could probably get it higher with a roof tripod. Put it 
on a part of the house where the creaking, clanking and 
moaning won't bother you. Reinforce the roof trusses.
