I also wonder about the design of the joints on aluminum towers. Both
Universal and Height have the same design with the wider part below the narrow
part. That will promote ingress of water and lead to water inside the legs. I
sealed all the joints with liquid tar before I raised the tower. I hope that
will keep the water out. Maybe there is a reason for this design but I failed
to understand why.

I wondered about the design also. I think they went that route so as not to
make the tubing any thinner. Mike

I have owned a few Universal towers. I had one at my Aruba home along with a
Rohn 55g tower, guess which one did not require frequent painting for
corrosion maintenance? N9IWW is apparently looking for an aluminum Rohn 25.
A 12" Universal tower is not very strong. The Universal Tower joints are a
poor design, in my opinion. They upside down so water and dirt collect
inside them and the supplied cheap zinc plated hardware will quickly
disintegrate.
