Dick (and the reflector), At the risk of sounding crabby (while I can be, I currently AM NOT!) ... Call your local oil and lubricants distributer, and give them the technical specifications on your n
Tom, Try looking in the phone book under steel service centers (two in the area here are O'Neal Steel and Tull Metals). In many cases, they scrap out pieces shorter than 20' (they're called drops), a

Mike and gang, for small gears, couplings and the like, check out Small Parts (in Florida I believe). My catalog is in the shop, and I'm not ... if you can't find them, let me know! Might be the answ
A metal roof is indeed a wonderful groundplane for a vertical antenna. In the early 1980's I installed a 35' marine whip antenna and an automatic tuner on the top of an aircraft hanger in Sacramento,
Bob, You might consider using a marine fiberglass HF whip antenna (Shakesphere makes a nice 23' job) fed with an automatic coupler (such as the SGC) at the roof. You'd still have to install a counter
The shakesphere 222 is not loaded, the bottom section has four copper straps buried in the fiberglas (as I remember). During my active duty in the Coast Guard, I've seen the 222 used on both ship and
What you are describing is inadequate project management, not incompetent professionals (although the cable installer may well have been lazy!). You need to SPECIFY what you expect, INSPECT what was

Check with your local motor rebuilding shop and have them cut the brushes for you. Our local "Fleet Hardware" can handle this task on a walk-in basis. It DOES help if you have the old brush and an ap
Malcolm, To work around the 5:1 diameter ratio, model two Rohn 25G towers side by side, connected at the top. Better yet, model (and build) the drop wire as three wires spaced just like the Rohn 25G

Dick, Well said ... I too look for TOWER and ANTENNA information on TowerTalk. Having said that, many of us learn by reading and asking questions. Rather than sending someone away (in a huff perhaps?
Hi Tom, Phosphor Bronze wire rope is what I've used for shipboard wire antennas when I was in the Coast Guard... along with matching hardware. (Yes, I sure DO know how to spend other people's money!)
