My antenna's are really pretty basic. It looks more impressive on paper than it really is. I have friends here in my area that do have crank-up towers that reach 100 feet plus and don't require guy wires.
One of my friends has a 120' self raising/lowering tower. He pushes one button and up it goes, or down it comes. He has 22 antennas on his tower (I counted) for everything from the VHF bands, HF bands and into microwave and gigahertz. His shack is damn' impressive too. He restores old Collins equipment which takes up two walls in his 15'x15' shack. The rest is all Kenwood. Everything's on a remote control too. The guy's a genius.
