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.
