[TowerTalk] Pneumatic Mast

[Chufo, Robert L.]

I am trying to find a source for the purchase of a pneumatic or mechanically
elevated mast/tower. It should be self supported. I need to elevate 2 pound
ultrasonic wind velocity meter to heights of up to 35 feet..or more. It will
be used for air velocity measurements in underground mines so weight and
portability are important. I built a pneumatically elevated mast over 30
years ago for signal strength measurements and was hoping to find a source
where I can purchase one so I won't have to construct another.

Thanks,  Bob  K3ZAU
