This thread reminds me of the "Sad Tale of Joe Spinoza." I'm sure a few of the "old timers" on here remember Joe? Joe lived in Concord, CA, not the easiest place in the state to erect a tower unless
Are you pulling our leg(s), Ed? A GUYED compressed air tower? We (Mt. Diablo ARC) had a compressed air tower on our emergency com trailer for a few years, but it was definitely a portable operation,
Bill and all, This is probably no secret to most of you, but true 9913 and other air-dielectric cable (Flexi-4XL, etc.) is fragile stuff. To get the benefit of the lower loss you need to be sure you
Butternut (the vertical, not the coffee) had some stuff called Butter-its-not (or something like that) that was specifically for that purpose. I have purchased it in the past from ham vendors. The st
Hi Gene, As you know, I'm planning on this type of tower. I've been looking at the foundation options and I really don't want a 9' x 9' (or even an 8' x 8') concrete pad under the tower (the Solid Bl
I used a Carolina beam (similar to the Carolina windom, but with the ends turned down bobtail-curtain style) for a while and was very impressed with it, but to the original question... Can you use a
I installed a used UST a few years back. The calcs were done to an obsolete UBC so I had to get them redone by an engineer. I don't recall the context now, but while we were discussing the installati
I've been discussing cylindrical vs. cubical tower foundations off list with a couple of the TT guys. I was finally prompted to dig out my old engineering calcs from the US Tower MA-550MDP tower I in
The GC-038 mast clamp is shared by numerous Yaesu rotors including the 800, the 1000 and the 5400 series (AZ/EL rotors). On the 5400 series at least, it is the same clamp on the top and the bottom. T
OOPS, I take that back. The 1000 user's manual DOES show a "pole mount" option, and it does use the GC-038 mast clamp. Sorry for the confusion. 73 - JC, k0hps@amsat.org --Original Message-- From: tow
You may not even need to call a lawyer. That could cost you the better part of your settlement. IF you want to go after the neighbor (and that's a big if) and if your state has a reasonable small cla
Hi Scott, The TH6DXX (plus a 5L 6-meter) is a good amount antenna so I'm not sure about that, but here's what I did to support some smaller antennas. Perhaps it will give you an idea. When I was putt
John, How did you make your "thrust bearing" watertight? 73 - JC, k0hps@amsat.org pipe When I was at the University of Missouri a group of us lived in an old, 2-story house, with a HIGH attic. I bolt
How about coiling them neatly (so they will drop cleanly) and tying them to the horizontal member using a couple of those long, skinny kids balloons (like the balloon artists use to make neat little
Has anybody dealt with F12 recently? Are they having problems with their website inquiries or is it just me? Assuming I can still get one, I'd be curious to know anyone's experience with the F12, EF-
Does anyone know of a steel tube distributor in Northern California? I seem to remember a company, Tube Services or something like that, in the San Jose area, but now I can't find them. I need a long
Greetings fellow TTers, Last summer (when I still hoped I could get my tower permitted and erected before the rainy season) a couple of you responded to one of my questions by suggesting I contact or
Hi Lee, Just a couple quick suggestions/comments, you'll surely get many more. If you have or can get an antenna analyzer, try it right at the antenna, without the coax. Lossy coax will show a lower,
I'm installing a new 80' tower this summer. It's in a location that can't be accessed by a crane so I'm going to build it in place like a giant erector set. (I'll post a link to photos soon.) I know
I agree. I built a St. Louis vertical for a club picnic a few years ago. Even with eight tuned radials we couldn't hear a thing. The band wasn't all that active at the time but it was so quiet we won
