Here are the specs from US Tower
9 sq ft with 65 pounds for 70 mph winds.
22 sq ft with 100 pounds for 50 mph winds.
What is your wind zone. I would hope that you would have the tower down
when not in use.
Seems like a reasonable solution.

Subject: [TowerTalk] US Tubular tower
I must use a tubular tower in my location.
I plan on installing a 55 foot US MA 550 tower with motor pull-down drive.
I have tentatively decided on a Steppir two element beam (specs aren't too
shabby for such a short boom) either bolted directly to the end of the top
section of the tower or only 6 inches above the tower on the mast. The mast
itself would have a total length of 10 feet with about seven feet protruding
above the tower. At the top of the mast would be an Optibeam 40 meter
rotatable dipole. Total wind load would be about 7.5 feet with a total
weight (not including mast) of about 50 lbs.
How does this sound? Is the MA 550 up to it? I think this is the best I
can do at this location and still get a forty meter antenna up at acceptable
height.
Your thoughts would be appreciated.
Tnx
