Sorry to clutter up the reflector with yet another post on this subject, but I really can't let this go without responding. I think that under certain circumstances it's completely appropriate to sen

let's seen I don't think this is correct. I believe that the tower cross section is included in the standard engineering calculations to determine maximum antenna wind load. I'm no PE, but it looks t

As long as we're back on the subject of hanging coax, can anyone tell me the best way to attach RG-213 or equivalent to the top standoff arm on my U.S. Tower tubular crankup? The standoff has the usu

Yes, that's essentially correct. The main cable runs from the winch to a pulley at the top of the fixed bottom section. From there, it goes down into the tube alongside the middle section. I'm not e

I agree. Besides, now that you've told us all how to subvert it, the filter is useless... 73, Dick, WC1M --Original Message-- From: Dick.Flanagan. <dick@libelle.com> To: K7LXC@aol.com <K7LXC@aol.com>

You might also consider Time Microwave LM400UF (Texas Towers and others have it.) It's another semi-flexible foam-filled low-loss coax. Price is comparable or better than 9913F. I think the numbers s

That's an interesting idea that should work in theory. I haven't dissected the motor/limit switch circuitry in the tower relay box yet, so I don't know exactly how it works. I suppose the limit switc

That was easy. Now, how can you broadband a low (say, 60 feet up) 80M dipole or vee enough to cover 3500-3900? Is the "coaxial resonator match" the only route? 73, Dick, WC1M --Original Message-- Fro

The Ameritron 4-pos antenna switch accomplishes this trick. It sends low DC voltages down the coax to operate the antenna switching relays. I know it uses some RF blocking capacitors, but I can't rec
