I'm not sure that you need 3 sets of guys with an 80' Rohn 45g tower. I
think two sets is enough and if you wanted more strength you could upgrade
to Rohn 55g. I have owned several Universal towers from 30' high to 70 '
high and I recently installed a 50' one at P40A. Aluminum does bend more
than steel and climbing them can be scary for some. With a guyed tower
you do need three additional holes for the anchor rods, however you still
wind up using less concrete than with a freestanding tower. There also
steel freestanding towers available like those from AN Wireless and Trylon.
A lot of the decision will be based on if you have room for guy wires, how
objectionable you find their appearance and what fits in your budget.

I recently retired and am planning to re-locate to Tucson, AZ (from
Lexington, MA). I am in the enviable position of rebuilding the shack
and putting up a new antenna system.
At present, I have narrowed the choice of towers to either 80' of
Rohn 45 or an 80' Universal Aluminum Free-Standing tower.
On top I am looking at a Tennadyne 8 or 10 el HF Log with a 6 Meter
antenna above that (10' separation).
The Rohn is the "classic" approach but the Universal is very inviting.
First, no guys are required but it takes a lot more concrete in the base.
Also, not sure how easy it would be for two guys to climb it to install
the antennas.
The Rohn, while adequate, has it's drawbacks. Namely three sets of Guys
and three more concrete piers.
I would appreciate comments on my "predicament" and suggestions are
welcome.
Thanks,
73, Dick, W1KSZ
