Wishing to brag; check out my new 40M antenna & tower erected this summer/fall. It really works well. The website pages have a lot of info and piks of the tower install, the antenna mods, and antenna
noticed from the great pix KB9CRY posted he used some weights to We couldn't find a heavier weight at the time so what you don't see in my piks is how the far set of weights is attached; they are def
I would agree using a motorized vehicle, whether it's a tractor or car, to pull up an antenna or tower section either on a gin pole or other is dicey. The problem is that you don't have feedback in t
After 46 years, I'd replace the nuts & bolts with new. Don't take the chance. Phil KB9CRY _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers",
I don't want to take away from the guy vibration eliminators; supposedly they do work but they only reduce vibration induced into the guys from the wind. I think the original posters of this thread w
Right. What exactly is the antenna? How far up the mast is it mounted? What is the mast material?. Is there a thrust bearing at the top? Was the antenna boom pointed into the wind or sideways to it?
As I found out here in unincorporated Will County, Illinois, I really didn't need any permit but as I convinced the reviewers that I was going to be pouring concrete with rebar and they needed to ins
I agree. Check with the HamLaw reflector folks but I don't think a casual conversation with the city planner would be considered to be legally binding. You either need a copy of the regulation that s
I'm no expert but I'd be leery about a nonconductive tower. Polyphaser specifically recommends against them; probably because of the large potential difference between aluminum at the top of the towe
For my two self supporting towers, we had a crane so I attached the antennas to the masts before hoisting and just lowered the whole assembly from the top down. For the 120 ft. Rohn 45 we just put up
I don't want to beat this to death but as others have pointed out, the NEC only recognizes mechanical or exothermically welded joints. Solder is not. Solder will melt during the first high energy sur
How about one of you telling the rest of us what we need to purchase, what the stuff is called so we know what to ask for, what we're going to need and how to use it? OK, I'll take a stab at it. Ther
You're right Rich. I've developed the technique. I hold the torch's tank and stand with two feet spread apart and crouch over and light and get out quick. I've never had any problem but I do agree th
ith the stub mast mounted to the rotator and top bearing is there any need to ground this stub mast independently to the tower or will the thrust bearing/rotator provide an adequate path? Theoretical
And if I may also add couple of other categories. There are those hams who : 4. Do it the right way, in accordance with manufacturer's recommendations, and those who do not. How many installations ha
Marc, I haven't yet fixed my R5 but here is a website that has a lot of useful info. It seems that maybe you've already done some of the mods/repairs listed here. My bet is that if you've got bad SWR
Yes, antenna elements will not be falling through the roof! And buy an AlfaSpid worm gear rotator with no brake therefore no noise, if that's a problem. If the tower is designed to be self supportin
As a trained Health & Safety Manager for the plant and the company, I know of no OSHA climbing certification requirement so to speak. They do require that employees be trained in all elements of OSHA

Actually I was talking out of turn folks. Ask the manufacturer what to do. I'm a full proponent of doing what the manufacturer suggests, period. If one wants to do their own thang, then get a profess
