Tell them you are using the tower itself as a vertical radiator. It would be hard to argue with that. I have 127' of Rohn 25 on my property. The guy wires are broken up with insulators and the whole
I have not been too impressed with "cold galvanising". I found that it begins to rust through after a year or two. I have had much better results with Rustoleum "rusty metal" aluminium paint. It see
I use only three guy anchors for my tower, which has four sets of guys. It would seem to me higgly unlikely that a guy anchor would fail, but I have seen it happen. That's how I acquired my base insu
The best way to solve the problem once and for all is to feed the dipole with open wire tuned feeders, using a balanced, link-coupled antenna tuner. That way you can instantly change the resonant fre
I use a piece of 2" wide heavy gauge copper strap which surrounds the base of the tower in a rectangular ring. The radials are silver-soldered to the strap, and there are 4 pieces of strap soldered t
Probably a Rohn Clone. I have seen many of them. A lot of local welding shops made up towers for >the farmers to get a TV antenna up high enough to get the signal from the Big City. In my area of >We

But if you are talking about just a few inches to get through the wall of the house, the loss shouldn't be any higher than with feed-through insulators. I would use some larger size coax than RG-213,
Even "remote" doesn't come with any gurantees. Purchase 20 acres, set up a remote with antenna farm, developer sells land around you, large group of fancy homes go up, form a HOA of which you aren't
Has anyone heard anything about the FAA easing up on tower lighting requirements recently? I have noticed within the past month or so, the red lights on nearby structures have gone dark at night. The
I recall reading an article in a pre-WWII radio publication about raising a 100-ft tower entirely with a gin pole, requiring no climbing or crane. The tower was fully assembled on the ground, and the
The 1952 handbook has a real nice unit. Swinging link is old stuff and obsolete. Use a fixed link and a link capacitor to tune. I had one of those with the swinging link. used it to pivot the link ou
From: "bill rubin" <brubin2010@gmail.com> The intention here was not to "bitch-about-the-government" but rather bring attention to the issue(s)... If any HAM wants to put up a tower why should they b
I would always encourage hams to share technical information on their equipment, whether home built or commercial. When you buy a product you are not obligated in any way to keep its design confiden

"I own a 43 acre lot in Maine and was preparing to put up a few towers. That was until this spring when I was contacted by a firm putting a wind farm on Stetson Mountain the next county over. The pow
I once put up a couple of 50' TV push up masts (actual height 45'), with two additional sections of 10' TV mast on top of that. They made very nice 65' masts for a 160m inverted L, one for the vertic
If I were a hermit type, looking for a retirement home, with few other interests than ham radio, I'd consider it. The economy in that part of Maine sucks, but with my SS and TN state retirement, I co
The base insulator doesn't have to be expensive. Look for a used AM broadcast tower insulator. When I put up my quarter-wave vertical for 160 back in 1980, 127' of Rohn 25, I was able to purchase one
