Bill:
Your requirements that the antenna support structure be both non-guyed
and a single pipe are somewhat mutually exclusive unless you decide on a
short tubular tower like the US Tower MA-40, but kept at 30 feet. (It'll
run you $849 from HRO, per their QST ad this month.)
If this won't work, I can suggest using three sections of Rohn 25
bracketed to your house (with appropriate internal reinforcement of the
roof/wall), sunk into the ground about five feet, with five feet or so of HS
steel mast plus your antenna/rotator. That ought to keep it invisible from
the street. The Rohn catalog claims that their sections have some amount of
self-support ability above a roof bracket. But the expense of three
sections of 25, plus two brackets plus reinforcing, etc might cost you
nearly as much as the MA-40.
Nevertheless, congratulations on your victory! Hope to hear you on
with the new aluminum soon.
