It seems to me if the woods was thick enough to look like a solid wall of dielectric at HF, neither light nor people nor animals could wade through the mess. I'd wager there is NOT an abrupt change i
still in antenna. Only if one of the trees falls on a guy wire in a storm. about 65 ft It will not. I highly recommend ON4UN's new book, "Low Band DX'ing." It tells how all this good stuff works. In
Very aptly put, Jeff! It is disconcerting, to say the least, to come into the ham shack and hear music coming out of my computer! Perhaps this is a wake-up call to us non-geeks that outside sources c
Product review from third party: When we put up my 199 foot tower, I got a good chance to play with the model 90 and the PT-2 units. All the guys were tensioned with a very expensive guage to 400psi.
I had always wondered about that! (I was very bad at math in school) Many thanks, Brian. Does each guy exert the same downward weight regardless of its length, or do longer guys produce more? Does t
I always like to pass along good prices when I find them. WB0W, www.wb0w.com is selling MFJ-259B's for $189.95 I have no ties with the firm, and have never met anyone there. I just saw the ad and nee
Actually, I paid $249 for all the above plus the power cube. (((73))) Phil, K5PC -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk@contesting.com Administrative reque
Definately use the strap, but come off the tower a bit higher. You want about a 45 degree angle from each tower leg to the three ground rods. Do not turn the strap 90 degrees under the bolt on the to
I have been around RG-58U since it came out! After several bad experiences years ago, I have limited my use of it to situations that it was designed for.... receivers and test leads. Try replacing th
Hi Tom, It is not the loss on 10m that is important. RG-8X is only rated at 360 watts @ 30 mhz. (((73))) Phil, K5PC l -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk
Please post the power ratings on LMR vs Heliax @ 1.8 and 30 mhz. This data is nearly impossible to find, and usually not included in QST and CQ ads. Many thanks! Phil, K5PC -- FAQ on WWW: http://www.
If you check the Rohn specs on tower/guy alignment, the tolerance falls somewhere between transit and hand grenade. The purests will vote transit in your poll, but Rohn is a bit more liberal for the
Good morning, Mohammad, A thrust bearing mounts on a rotor plate above the rotor, or at the top of a flat-top tower. It has ball bearings inside and set screws to tighten into the mast. This makes th
I just installed Dimension 4 out of Cinncinatti. Great program! It runs hidden or minimized, and resets once, or every_ minutes. It is freeware. See it @ www.accessone.com/~thinkman/ It has been "rig
I want to construct a Bob-Tail curtain for 80 meters. I have read ON4UN and all the other books I could get my hands on, and many questions are still unanswered. 1. What should the radial system (opt

I had a similar problem when I installed the 2 element version of this antenna. It turned out that the balun was faulty. Disecting the balun revealed no problems, but when it was promptly replaced by
The connected balun with an open end added several pf of capacitance shunted accross the feedpoint. The real test was when you disconnected it entirely. 2.75/1 vswr with the antenna setting within 50
