I'd call Chuck at Tennadyne and ask him. The T8 and other Tennadyne LPDAs have square aluminum booms that are insulated from their support mast because the booms themselves are the lines which connec
I'm puzzled as to what kind of instructions anyone needs for a tower. Isn't buying the correct base and installing that in the prescribed hole and amount of concrete all we really need to know? I've
Re: Amphenol PL-259's... Amph does make silver-plated PL-259's but they don't have the Teflon dielectric. They make "Astroplate" (shiny nickel) PL-259's with Teflon dielectric, or silver-plated PL-25
[Steve Katz] You didn't say how long that cable was going to be, or what is supporting the quad. The best choices for transmission line usually take into account the frequency of operation, line len
Hi Jerry, I don't know anyplace in eastern PA, but if I lived there, I'll bet I'd find one! Here in southern California, my usual source is Apex Electronics, 8909 San Fernando Road, Sun Valley, CA (8
Re: RG17... The center conductor doesn't shrink and withdraw the center pin. It, along with the dielectric, can literally slide inside the braided outer conductor and create the effect that you see,
How does a pigtail go bad? Maybe when the pig finds his tail out partying all night, etc...... Never had pigtail ends go bad, in 37 years of making them and probably 500 installations by now. After m
All one needs to do to be completely safe when climbing any type tower of any height is to be young. The young are immortal. I must have been, since in my teens I climbed lots of 100+ foot towers wit
Yep. I can't believe I climbed K2BPP's 180' R-45G with a belt that wouldn't go all the way around the tower, so I just climbed it with the belt around my waist, and around nothing else...twice. I did
Hi Tom, Sounds like the "professionals" who did these government installations were unfamiliar with gravity. RG17 and similarly constructed cables cannot be run vertically for any distance without a
I have a W9INN 130' (or so) loaded dipole. Not bad. 2:1 VSWR bandwidth appears to be about 25 kHz, but even a full-sized job is only about 50 kHz. I'm using coax to feed it, but if I was serious, I'd
Hi Lee, Sure: It's Cinch Connectors Inc., Lombard, IL 60148-3230 -WB2WIK/6 "If everything seems under control, you're just not going fast enough." - Mario Andretti
Type "end" connnectors? I think you'll find RG8 coax doesn't support operation at 5.8 GHz, so it won't matter much what the connectors are. You need 100% shielded cable, preferably rigid coax. For su
[Steve Katz] MFJ has a "no matter what!" warranty on all their products. So, I guess if you fall a hundred feet and splat onto the patio below, they'll cheerfully replace the tower. -WB2WIK/6
[Steve Katz] Perhaps. However, if you suffered Death By Tower, then you'd never know if the claim which followed was entirely successful or not. -WB2WIK/6
Hey Guys, your old TH7, T2X or whatever is now an MFJ model...scary as that might be. -WB2WIK/6 "If everything seems under control, you're just not going fast enough." - Mario Andretti
To steer this back onto the forum topic... How many people think that if we can take all our elected or pseudo-elected politicians and throw them from the top of 180 feet of Rohn #55, we'd all be bet
[Steve Katz] Wow, that's a 650' long antenna (5/4-wavelenth at 1.8 MHz. The wire will have to be very strong to self-support for this span. Whis is probably why almost nobody has one. [Steve Katz] W
The SteppIR is catching on and seems to have a loyal following, so it's a success. However, here are the LPDA advantages that I find, as a user: -No moving parts to wear out or fail -Maintains excell
