321. Tower bolts (score: 1)
Author: w7ni@teleport.com (Stan Griffiths)
Date: Tue, 17 Dec 1996 17:36:45 -0800 (PST)
A lot of you guys seem to be pretty casual about what bolts you use for bolting Rohn towers together. The criteria seems to be "if it fits, use it" and "if it doesn't rust, that has to be better". Wh

The big problem, if you are talking about 25G is the fact that you can't mount the rotator plate anywhere there are diagonals. This means just below the top or at the junction of the top section and

Because if you knew how little it would take at 70 mph, you wouldn't buy it. I believe most of the freestanding crankups I have seen would be lucky to stand there extended with NOTHING on them at 70

It will be a LOT LESS THAN HALF. It will be half if you assume the tower itself has NO WIND LOAD AT ALL. The tower itself probably has a wind load equal to the antennas on it. To me this means that

I see specs on crankup towers and how much they will take on this reflector every once in awhile quoted from old brochures and manuals for towers made by companies who are no longer in business. I ca

My God! You mean its quad vs Yagi time again? My advice would be to go with the advice you get from the guy with the best performance record in CONTESTS (not DX). If you are contesting (as opposed to

I don't think so. The antenna is doing exactly what it is supposed to do--create a strong RF field. The phone is NOT doing what it is supposed to do--ignor the RF field. I have a big amp and I can g

I wouldn't think of suggesting you trade in your wife on a new model. However, I would suggest you take up another dastardly pastime so your wife can realize, on her own, what a great hobby ham radi

Here's one more "con" for a log periodic I didn't hear mentioned. A log periodic will radiate a harmonic or parasitic that falls within its bandpass just like it were a desired signal. Other antennas

If you are talking about Rohn 25, there aren't a lot of options about how much mast to put down in the tower. The rotator will only mount in certain places since the standard Rohn rotator mounting s

This is very similar to what we have to put up with in Washington County, Oregon. It is over $2000 and requires a "development permit" since there is no other way to handle it in their rules and reg

I agree that you should not use a tower section or short tower base buried in concrete if you think water can get into it from below and rise to the freezing level. A flat base with a pier pin means

Hi Gene, I think the number is 2/3, but I don't know the origin of it. One caution when using this factor to reduce the area of round members. I noticed that there are TWO figures for wind loading c

Yep. Put in new anchors and don't wait for anything. For towers this large, I put in anchors with 8 foot rods and go down about 6 feet. I don't think your anchors are up to the job . . . Hurry! Stan

Unmodified prop pitch motors were designed to run off of the normal aircraft DC supply of 28 volts. However, they will also run off of 35 volts AC at 60 Hz. They take about 10 amps or so. I understa
