261. [TowerTalk] I Beam Base (score: 1)
Author: Wilson Lamb <infomet@embarqmail.com>
Date: Sat, 27 Jan 2018 13:08:53 -0500 (EST)
WOW, what an appealing idea! It's fun to be on here and see such things pop up! Imagine an antenna dragging at 200 lb, 100' up, and you have 20K ft lb at the base. Then add for tower, a few times tha

Author: Wilson Lamb <infomet@embarqmail.com>
Date: Thu, 8 Feb 2018 09:52:03 -0500 (EST)
Of course errors creep in. I expect the staff has to scramble to sell ads and get QST out. The real answer is for us complainers to submit some well reasoned, researched, referenced articles! I'm wor

Interesting stuff about pulldowns, etc. FWIW, I have used a couple of small units for yard work, raising Field day towers, etc.. I have had both Harbor Freight and Northern Tool winches and feel the

Neat method for installing reducers. I've been known to twist the braid tightly and fish it through one of the holes... Wilson W4BOH _______________________________________________ __________________

Date: Mon, 19 Mar 2018 12:46:06 -0400 (EDT)
Really? Have we lost it? Almost $50 for a clevis? Three of them cost more than a tower section? 12,000 lb rating? What size EHS are you using? How about a foot of guywire instead? It seems a little d

Soak heavily in magic juice. Maybe wrap in a rag to maintain concentration of juice. Get cheap box end or socket wrench. Make torque pulses with hammer or impact wrench. Repeat. It seems like there w

Author: Wilson Lamb <infomet@embarqmail.com>
Date: Mon, 30 Apr 2018 14:24:17 -0400 (EDT)
It's painful to read this stuff. The spec's are regularly revised and interpreted. They are based on model(s), history, tradition, and probably rules of thumb, backed up by calculations to three deci

Author: Wilson Lamb <infomet@embarqmail.com>

Not a tower, but might be mounted on a tower... Does anyone have an Andrew catalog from 1999 or a little later? I'm looking for a datasheet for a dish, model TSBA1. I think it's a 2.4GHz antenna and

Beware! The duty cycle of cheap PM motors is very restricted. Better at light load, but should be considered. Drum capacities are severely limited. Wireless? Are you kidding? How will you feel when t

Nothing to do with towers, but interesting... Last spring I went through this, with the help of W3AHL, who is an EZNEC whiz. I read and reread the ON4UN Low Band DXing chapter AND the ARRL chapter an

WOW, was there an answer there? As the OP surmised, staking involves some sort of hammer work or other damaging means. I have staked nuts by driving the corner of a chisel into the corner where the n

Date: Sat, 10 Nov 2018 11:44:37 -0500 (EST)
Putting a dummy load out on a feedline does not mimic driving an antenna. And tuning in the shack only makes the amp happy. It doesn't change what is going on outside. SWR due to line problems or mis

The choke is essential with small numbers of radials. Friends recently helped me with a great T Top loaded vertical for 160m. We used 57' for the vertical element and four 75' radials, up 7', and a s

All that big rotator stuff is more work than I would do. However, If I were doing it and had long runs I'd look into using 120V for the long runs, with appropriate transformers at the ends. I can eve

I'm really lazy sometimes, ok ok, usually. Have you been talking to my wife?? I wanted a quick end fed antenna, so brought it, about 150', into the shack through an Al clad window. The wire was prett

OK, that's about it. Of course I can estimate, but wonder if anyone has a CG location for a nested tower, horizontal. Yep, I'm calculating ballast for my 16' trailer. Weight is trivial, but stability

Author: Wilson Lamb <infomet@embarqmail.com>
Date: Tue, 26 Mar 2019 12:34:48 -0400 (EDT)
Torque will be induced in a tower if wind blows from a direction not parallel to a guyline. As the tower leans, it will cause differential changes of guy tension, which will twist the tower. I have n
