Hi Kenneth, I have a 90~ish Ah deep cycle battery, kept charged by a trickle charger, which is only a 500mA or so 12-14v wall wart. The wall wart is inside an outdoor outlet, and the battery is in a
How recently? I had an email conversation with someone from HyGain about a week ago and they no longer sell towers, despite their web page showing that they do. Chris KF7P I just noticed that Hy-Gain
That doesn't surprise me at all...I really wonder if the HygainCushMFJunkVectroAmeritrunk factory is just full of baboons. Chris The interesting part is you can actually order one, pay for it and pro
Don't forget that strengthening the mast so it won't bend means that force is now presented elsewhere, i.e., on the tower itself. Make sure the tower can handle it. Chris KF7P _______________________
It appears this has become a "I love my antenna" pile-on, so here's my .02. Since the original question was for multiple beams on a very tall crank up (89'), You can get almost all bands on one boom.
We recently picked up a UST TMM438 (I think) with four guys...just put some 2x4's through the tower at the front and back, using them as handles and just walked it off the trailer. It wasn't hard at
These take care of that kinking problem. http://www.kf7p.com/KF7P/Pic_arms.html Chris KF7P _______________________________________________ _______________________________________________ TowerTalk ma
Jim Sez: Bond your copper grounding wire (which comes into the concrete through the top)to the rebar cage. or run 20 feet of the copper wire around through the concrete, as long as it's totally encas
I wonder why no one has come up with a clamp that uses a bolt that tightens a spring, so there is constant tension on the clamp, just like exhaust manifold to collector pipe bolts? Guess I need to ge
I don't think there is any difference. Chris KF7P _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http:
I don't like the bottle the Noalox comes in, it's kinda flat and hard to get any grease out of it when it starts to get low. But that's pretty nit-picky. Chris _______________________________________
This reminds me.... Recently I decided to clean up my 40m beam to get it ready for installation. I bought it used (a couple years), and I thought it would be good to take apart every joint, clean, re
Have you tried modeling the array and seeing how the model SWR reacts when you add reflectors/directors? Curious. Chris KF7p Hi All Been playing with an antenna here. Some time back I put up a vertic
Yup, what he said. Also it allows you to move the rotator plate to a different vertical position if you want. Chris KF7P That is how the Rotator plate is mounted in Tri-Ex/Tashjian Towers, why would
Okay so how do you route the coax back to the mast from the driven element then? Dangle the coax below the mast? Add another choke at the mast? But wait! The mast is metal too! Just how much of a pro
Oops, I meant dangle the coax below the boom. Chris _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com htt
The wood spacer is a good idea, maybe Jim can chime in on how much spacing is needed. This is a real problem with double boom log periodics since both booms are hot with RF, and running the coax alon
Wow, that looks like a project, and I do believe it was a trailer tower. It's got the mega flanges welded up a ways on the bottom section. Most definitely a USTower, or their predecessor Tristao. How
Portly Patrick's Popsicle Package. $2 per. Chris KF7P How come all tower Mfg.'s start with letter T? That is the perplexing thing. Chris KF7P Alliteration, an advertising gimmick in this instance. __
