You'll get that kind of reading if the ends are too close together. If your antenna is U shaped, or V shaped, then that is the problem. Antennas that zig and zag around should have a low swr, as long
This doesn't sound like a good idea to me. I use that small RS type mast that you can also pick up at hardware stores cheaper, and cut it to size, drill some holes for u-bolts to attach it to the tow
I'm strictly low profile here, but a couple of the really big multi tower contest stations here in IN are using Polyrod. Mike K9MI -- Original Message -- From: <Cqtestk4xs@aol.com> To: <n7ua@ix.netco
Julio, I'm indeed no expert, but I would say 10 ft would probably be more then sufficient. In actual practice, our local radio club has the 6m beam only about 5 feet away from our hf beam. I wasn't i
If there is Tom, it hasn't got anything to do with rain. 450 ohm changes also. 73, Mike K9MI _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers
It basically is the same thing Bill. It can be a resonant length for a certain band if you want it. But it does not have to be. Just be sure that it is at least "close" to resonant size on the lowest
Scott, I was QRO for about 2 months, but my antennas are just too low (40ft) to keep me out of things. The tuner I used then was an Ameritron ATR 30. I used it with a W9INN 40/80/160 to fit my small
A "google" search brought up this site: http://www.nyeviking.com/productsaccess.htm The least expensive was over $800, and for all, it warned that it might not tune some antennas on 160. was a bit sa
By Sixbanders, I take it you mean the SteppIR antennas, right? Easy, just compare them on 20, 15 and 10 like the other antennas. I think at least the contest crowd doesn't worry too much about the ot
I may be completely off base with this, and if I am, I'll apologize right now. With the Rohn BX, and HDBX series of towers, the "square foot" changes according to model. But I swear, I thought I read
What band(s) are they going to be used on and how long are they? Mike, K9MI _______________________________________________ _______________________________________________ TowerTalk mailing list Towe
Ed, you just need to spread the legs out. 90 degrees would be great, but of course if you can't do that, just do the best you can. 73, Mike K9MI _______________________________________________ ______
(snip) I'm> thinking I would prefer to have the strength of the insulation passing If I'm understanding this statement right, you don't plan on soldering the wire to the coax? At the center insulator
Not too rag on anyone's tower or anything like that, as I could have read this wrong years ago. But it has always stuck in my mind that Rohn said to not use any antenna with a boom length of more the
As stated at the begining of my post, I didn't want to make anyone mad, but I thought I had read that years ago. May you have many turns left, and 50 more years use of your HDBX56. Roger, thank you f
I recently purchased 70' of Rohn 25G from a friend who climbs on weekends. I'm replacing a 40' tower that is similar, but it is lighter and has the bars welded horizontal, and has no Z bracing. It ha
Thanks for all the input. I think with the way things are, I'll put the Rohn 25 up, but more then likely, at 40 ft also. I won't be gaining anything in the way of performance, but I'll at least have
Bob, I think I would just take some steel wool and buff up the connections. I don't think changing wall thickness would be a concern. Just so long as all the elements that go together are cleaned up
Scott, that's a nice antenna and I know you have to be anxious to use it. If at all possible, I'd wait until you can get a tower up even 30ft would be better then nothing. Towers anymore, unless they
Are you saying you cause RFI to 60 or 70 homes? Am I missing something here? Mike K9MI _______________________________________________ _______________________________________________ TowerTalk mailin
