[TowerTalk] Military Surplus Light Duty Crankup?

[Tony]

All:

I'm looking for a low-cost free-standing crank-up capable of handling a 
couple of VHF/UHF Yagi's as well as an azimuth and elevation rotor - 
something in the 30 foot range.

I thought about a home-brew crank-up made of heavy square stock but that 
doesn't seem cost effective. I thought I'd ask if anyone knows of a 
military surplus or some other alternative.

Thanks,

73, Tony
