Tony,
I suggest you take a look at the Heights Towers product line at
www.heightstowers.com
They make some real heavy duty self supporting towers.
Here's one example of a 77 foot tower with a motorized tilt over section that
will carry 35 ft^2 in 80 mph winds: http://w9sn.com/heights.htm

We have an opportunity at WP2Z to put up another tower. The owner of the
house would like it to be free standing. We would like to put up a 70' tower
so we could raise the height of the 40M beam (Cushcraft 402CD is presently
at 35'). Also it would give us a higher support for 80 and 160M wire
antennas. The only experience I have had with free standing towers is the
35' aluminum Universal tower that is holding a C3E. It used to be 45' high
till a hurricane several years ago came along and ripped off the top 10'
along with the tribander and rotor and proceeded to deposit it in small
pieces a few hundred yards away.
WP2Z is at 900' - one of the highest points on the island. And we are on
solid rock. So it will be fun to get a base dug. This QTH gets high winds a
lot. We have trouble keeping any kind of tribander on the one tower due to
the high updraft that occurs almost every night. The new tower will be about
100' away where the updraft doesn't typically occur.
Besides the 40M beam at the top and some low band wires I would like to
sidemount a couple tribanders - one fixed on US/Asia and one fixed on
Europe. We would continue to use a rotating tribander on one of the other
towers.
My questions to the group are:
- Am I foolish to try to put up a 70' free standing tower at such a
location?
- If not what's recommended for this kind of environment especially being so
close to salt water? I was looking at Universal Towers HD21-70, Trylon
T500-72, T400-72, AN Wireless HD-70. Are these overkill or fine or
substandard?
I realize that during a hurricane all bets are off no matter what we can put
up that is reasonable.
Tnx for any feedback. Trying to upgrade the contest station there to help
especially with our low band signal. Having both towers at only 35' is not
the best. Glad the owner is receptive to a new tower.
73,
N2TK, Tony
