Overkill! Are you guys even familiar with this small, light weight,
portable, aluminum "crank up tower"?!
If I was going to set up a portable unit, I'd get ne of these...maybe.
How thick do you guys think your average walkway on the side of your
house is...or a sidewalk...or a driveway?
Maybe because I've actually installed similar light weight towers, I see
things different.

I agree with N4ZR here.
Find out what is required, especially of the base. It isn't just
something
to keep the tower from sliding around. It is the _foundation_ of the
whole
tower. The house bracket can be thought of as merely an alternative to
guying at the corresponding height.
The base AND the bracket needs to be engineered by somebody who knows,
you
know, engineering. That definitely includes how the bracket is attached.
Even a small tower is a potentially serious thing. Do you really want to
have it toppled over after having taken a big chunk out of your roof?
Somebody who knows engineering can help with this. And, the expense need
not be all that great. Maybe 300 to 500 bucks. Cheap compared to a bad
outcome. Might even be needed by the local county zoning board anyway.
