Bill, I have been using a three stack of SteppIR's for one year in configuration close to what you plan on planning. Mine are stacked at 33, 66 and 100 feet on a 100 foot R55 rotating tower. The top

I have several in the truck and depending on the work pick the appropriate one: The good one is used for most lifting jobs. The cheap ones ($9.95 Harbor Freight specials) are used when I have to leav

Jim, I have copies of a few pages from the Basset Handbook of Rotary Beam Design for 1939. The Bassett folks had a series of commercial products like a 4 element 20 meter antenna with a rotor for $12

The Bassett literature calls it a antenna and never mentions the word yagi. Looks like 4 elements equally spaced along the "ladder-boom". The five pages that I have were copied from the original Bass

My capstan winch is made by MY-TE. It runs off 12 volts and works great. A friend has the AC powered version. Its reversible and comes with a foot-switch. The 12-volt version is great for taking sect

That's a pure winch. For tower work, a better solution is a capstan winch. Using a capstan winch, you wrap three or four turns of rope around the capstan. The operator applies 5 pounds force and can

Bob, One option is to get a can of Cold Galvanizing spray paint. I use the Rustoleum brand that's sold at Home Depot. If the surface rust is too extensive, you may want to have the tower sections hot

Hi Mark, That is very good customer service and really beyond the call since you gained no profit on the sale of the antennas. We look forward to working with the NEW Force 12. 73 Terry AB5K ________
