Roofs have trusses (some antennas too) - towers have bracing members. That's what confused me. a. A device that holds or fastens two or more parts together or in place; a clamp. b. A device, such as
years. This has been a recent thread. I suggest you check the TT archives at <A HREF="www.contesting.com">www.contesting.com</A> for LOTS of info. Go to List Search and type in <towertalk keyword> an
I was told this story by the owner of a 100' Rohn 45G tower who hired a professional and well-known tower crew out of New Hampshire to dismantle the aforementioned tower and he watched it while it wa
You're upset about 0.17 dB in a manufacturer's claim? Good grief. The margin of error on our tribander and vertical comparison reports was in the neighborhood of +/- 1 dB. Why not get upset with manu
that using off. The little cone-shaped devices are used to keep the ends from unraveling in cases where you would have ice coming down the guys. In your part of the country you'll never have that pro
Okay, I skipped over this part. Are you saying you took the Preforms off and reused them or you reused the little ice caps? You can't reuse a Preform after it's been installed for awhile (I don't hav
Which series - MA, HDX, what? Mucho differences between the different types. Maybe - see question above. What's the manufacturer's spec for the new base? Cheers, Steve K7LXC TOWER TECH
QSL. The legs of 25 and 45 are pretty thin. You might be asking for more trouble by trying to weld it. Cadwelding to the leg is strictly verboten too - good way to put a hole in the leg. I always agr
feasible to two clamped on A 16' aluminum mast is not a big deal. Why not just lift it up and drop it in the hole? Yes, it's semi-tricky. Yes, you need someone who can handle it. Just stand on the gr
Hopefully you're a graduate student (apparently not an English major). TH6? Vertical? TH6? Vertical? Go for the beam anytime!! And have a ball! Use the vertical as the backup ant. Cheers, Steve K7LX
Hey - knock it off. This is not a political rant-and-rave reflector. Let's please concentrate on tower and HF antenna construction topics. The poster sent his email to TT instead of cq-contest where
What's there to be skeptical about? You hold onto the rope and let stuff down. Your point about insurance is a good one though. MOST guys doing ham radio tower work do not have the necessary contract
Press the Wireman sells an 8-pin connector that works great too. I don't think it's quite waterproof but a little 33 or 88 tape should help that. Cheers, Steve K7LXC TOWER TECH
In 25 words or less? You can gather the steel costs yourself - check Texas Towers or other Rohn dealers. In general, the cost for the guyed system will be less - less excavation, less concrete, less
Don't forget that Rohn isn't the only manufacturer of self-supporting towers. They tend to be on the relatively expensive side whereas the Trylon Titan and AN Wireless versions are less expensive for
Correct. And the concrete base's function is to basically keep the tower from sinking. Which alignment are you referring to? You mean horizontal levelness? Plumb? The easiest thing to do to insure pl
Having just one template can be a problem as you've described. Using 2 wood templates is one way to get around it. What I do is to take the bolts attached to the template to my neighborhood welding s
