Won't work, Josh. Too much sag in the middle. My bobtails were between 100' towers and were just barely high enough off the ground in the middle. Are you planning to use the masts as radiators? If so
One problem here. 468/f does not work with insulated wire. You have to consider the velocity factor of the jacket. Otherwise, you will be chopping off pieces of the insulated wire to get to the desir
This is exactly what happened to me the first time I built a sterba curtain for 10M with insulated wire. Should have donated it to a CB'er. Tom, K5RC -- StripMime Report -- processed MIME parts -- mu

Just acquired a used TX6DX or DXX. Is there a clever way to identify if it is a DX or DXX? Is there a kind soul who could FAX to me the assembly instructions and bill of material? Thanks!!! Tom Taorm

<< The size of the 118,000 psi yield strength chromolly mast I posted is: 2 inch O.D. x 3/16 inch tk wall. I use an 18 foot length for my mast. It weighs about 80 - 90 pounds (I don't know exactly, b
Using aluminum mast is like bass fishing with 4 pound test line. It's great sport, but it is really frustrating when the big one breaks the line. Tom, K5RC/7 -- FAQ on WWW: http://www.contesting.com/
