To get a totally unimpeded 60% Fresnel zone, I had to go to 80 foot. I have some 25 sticks behind my barn, and pick up used ones from time to time for such uses. I hate guyed towers. :-) I'd rather limit them to 30 feet and attach them to a building gable.

Then, depending on how high he needs to go, suggest buying a tower that is at that height. A single SU would not need more than rg25 with guides since you have already suggested over 20'. IF he had to pay full price for Sat, he would be near the $500 range just for install and Equip. We all know it is junk! Last I checked here rg25 was around $100/sec. At that he could go at least 40 - 50 ft and maybe work?
