Launch Tower
Rohn 25 COTS tower components
In the past PSAS used a vertical person-lifter extended out to 13 feet as the support structure for the launch rail. This piece of equipment was large and cumbersome to move around, and so now a smaller piece of commercially available antenna tower section (a.k.a. Rohn Tower) is going to be used.
The 2004 Rohn Catalog (large 37 MB) can be found here.
