I had a 70' Universal Tower in IL and a 50' one in Aruba
http://www.qrz.com/db/p40a . In Aruba it held up very well to the elements
compared to my Rohn 55g tower which severe corrosion and required a lot of
maintenance. I replaced the factory zinc plated hardware with stainless
steel and I never had any bolt problems or hole elongation. I erected the
Universal tower at P40A using a gin pole as I did not have room to walk it
up and installation was easy. They do wiggle more than a steel tower and
are not as strong so I would definitely purchase one of adequate size for
your antenna. Carefully look at their specifications and don't overload the
tower.

I plan to install a 50' tower and a tri-bander for 20/15/10 and was
originally considering a U.S. Towers 55' crank-up model. While researching
towers, I came across a company called Universal Towers that sells aluminum
free-standing towers.
Based on the specs, the Universal Towers HD-21-50 aluminum tower looks like
it might be a better fit for the following reasons:
- * At $1989 it's $2K cheaper than the U.S. Tower crank-up
- * It only weighs 190 pounds (spread over five 10' sections), versus
>800 for the crank-up, making it a lot easier to get off the truck with
fewer people
- * The base doesn't require a rebar cage, making installation simpler
- * It won't rust
The HD-21-50 is rated at 21 sq.ft. at 110 MPH, while the U.S. Tower
crank-up is rated at 30 sq.ft. at 50 MPH.
The installation instructions for the aluminum tower says to assemble the
tower on the ground, attach the antenna(s), and then walk it up. In my
case, I don't have 50' of horizontal space to do this. Is it feasible to
climb this type of tower and assemble it vertically section-by-section with
a gin pole? (Whatever I put up will be installed by a professional tower
installer.)
Any reason why I shouldn't consider this aluminum free-standing tower?
- 73, Jerry
