Do you want a Rohn clone (Clohn?!?) equivalent or just another guyed
tower? There are several companies who have jumped into the vaccuum of Rohn 25
&
45 and several of them are directly compatible.

Is this for your ridge top QTH? Larimer County is an 85 MPH windspeed
zone so you'll need something substantial. Ninety feet of 45G is rated at about
22 sq.ft. @ 90 MPH so that should be plenty.

Har har. You'll never get a crank-up to be rated at 20 sq.ft. at 85 MPH
for a ham budget. A guyed tower is your best - and cheapest - bet.
I'm a dealer for the Nello Tower Co. 45G equivalent.
