It has to be a really STOUT tall tower to support more than a rubber duckie. Some towers wouldn't even support themselves at 110 mph. Absolutely. There's no where in the country that isn't at least 7
I looked at this too, in my catalog. I'd note that none of the 110 mph guyed designs in the Rohn catalog have more than 5 feet of tower above the top guy. Where as the 90 mph designs have 9 feet, and
This has been brought up over and over on TowerTalk. While using water methods (either the puddle technique described above, or the attach-a-hose-to-copper-pipe and push it in method) may be an easy
I've managed to locate a place for a bracket at 25.5 feet. If I had a gable on the side or rear of the house, I could probably go 5-6 feet higher. Mine is a two-story, with a basement. Maybe these de
I disagree, Steve. I don't think it means it cannot be done. Instead, I think it likely means that Rohn didn't think this was a likely installation. I'm sure that the Rohn tower materials are capable
Well, to take the Reflector (element #1) as an example: EC must be inserted over trap TA until the end of EC is 3/8" from the end of the trap TA. Just insert EC into EA until you end up with the desi
No one has their guys or brackets placed EXACTLY as shown in the catalog. Each installation has to be adapted to the environment it's placed in. Not necessarily. You may be doing something the manufa
Bill, this is certainly ingenious, but with 10 foot copper clad steel ground rods available at Home Depot for less than $10, it seems like an awful lot of effort. Perhaps if you can somehow get your
This thing says it has a 700 lb capacity. To be man-rated, I thought equipment of this type had to be rated for 10 times the capacity. It doesn't look hefty enough to hold 7000 lbs, so it would only
You know, in the aviation world, where lives are at stake if bolts don't stay in place (like those holding the propeller in place) -- bolts with drilled heads are safety-wired in place. This prevents
Actually, yes. When I first put up my A3S, I musta been in a hurry or something. The director outermost elements (eg 20m) were far too short. For some reason, I measured them wrong and they were abou
I built a simple circuit using a couple of diodes, a resistor, a capacitor and a 12 V relay for my 28-year old Ham-M. Works great. Bill Coleman, AA4LR, PP-ASEL Mail: aa4lr@arrl.net Quote: "Not within
Here in Gwinnett County, GA, we have different sets of rules for towers under 50 feet, under 70 feet, under 110 feet and over 110 feet. The requirements become more and more stringent as the tower he
Actually, blind fasteners are used on even the largest aircraft in areas where driven rivets or bolts are impractical. So long as the fastener has the required shear strength, there's no reason to av
