Good idea. I would suggest crimping the copper pipe (hammer it down) on the wires before soldering. As for those concerned that copper will deteriorate in the ground: if that's a problem, the ground
Not only is a perfectly balanced feedline an issue in minimizing radiation, but the antenna itself has to be perfectly balanced AFAIK. One side can't be closer to the ground than the other side, can'
Of course, it's hard to tell if the problem is caused by feedline radiation or antenna radiation. Sometimes problems are caused by the (desired) rf radiation from the antenna. Ken WA8JXM ____________
It is interesting how base requirements have changed over the years. Back in 1970, I had a 64' freestanding aluminum tower (Heights) with a tribander on it and other antennas. All the manufacturer sp
I am curious. All this talk about concrete strength, rebar, etc. Is anyone aware of a tower base failure due to strength of the concrete or lack of rebar? (Except for damage from a lightning strike.)
Are you saying that you paint the entire tower once or twice each year? _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTal
I believe it is a 3-2-1 mixture: 3 shovels of gravel, 2 of sand, and 1 of cement. I did my first tower that way (4'x4'x'4') mixed by hand in a wheelbarrow with a hoe. It took two days. The second tim
Mini excavators can fit through a normal doorway. Example, to enable passage through narrow spaces such as doorways and gates, the adjustable width track frame can reduce the Kubota K008-3s track wid
I think a BIG issue would be: what if your transmitter causes problems with their equipment? Intermod, overload, whatever. Don't be surprised if they write the contract in their favor. I also agree,
Is there any additional terminal charge when you ship to a terminal? Can you ship to any local terminal, or does it have to be a fed-ex terminal? There is a local truck terminal but of course they do
Those things are not cheap! Probably well north of a quarter million. Even the smaller skid steer versions are well over $100K including the skid steer. They just had a rubber tire mounted version ac
I know we have a solid layer of rock here at 42". Today I dug a base for a new HBX-56. Hit the rock at 36" BUT it broke up fairly easily and I was able to get down beyond 4' as needed. However, I am
Could you? Yes. SHOULD you? Probably not a good idea. It depends on the tree species and it's health. Some trees are shallow rooted and pull out easily. A 2' diameter tree is an older, bigger tree an
Well, that's a time honored tradition in American startups. Dell started in his college dorm room. Apple and HP in garages. I remember when Dell was under investigation by the Texas Attorney General
Yikes, I hope you aren't digging it by hand! Better hurry up and hope you don't hit rock! (I have a rock layer here at 40" down.) As for your original question, I find it amazing how requirements hav
For something freestanding, dxengineering.com sells 80m verticals made of aluminum tubing that might give you some idea of the mechanical requirements to get a freestanding 60' mast. They are not che
The sad thing is, I suspect those old towers are better than the new ones since Rohn no longer makes it. I bought a new HBX-56 and there was some light rust forming on the edges before I even got it
I recently put up a 160m inverted V and, in comparison testing, it has done well. I've been using WSPR reports comparing three antennas and the V has the best signal so far. The specs: --Inverted Vee
Wilson, I tend to support your view. Back in the days, there was little or no use of baluns. Look back at my 1960s handbooks and antenna books and the mention was rare and certainly not a mainstream
The homebrew was fun and exciting at its time but I agree a K3 is much more versatile and fun. I did play around with a number of 1 or 2 tube rigs when I was a teen and a 6L6 on a TV chassis was one
