I am told that this problem is worse on 45G than on the 25 or 55. When Rohn moved production on 45 from one plant to another they not only lost some experienced people but they lost an EPA "grandfath
Two things that immediately come to mind are the matching methods used, i.e., does it differ from one antenna to another and introduce a different phase shift; and distance that the driven element is
If you test the internal automatic antenna tuners in many new transceivers you will find, even on a relatively small mismatch, that you can get 100W to the load with no tuner and only 80 or so with t
Counterpoints if you please. I have tried every kind of attic antenna there is: dipoles, folded dipoles, G5RV, 8JK's, J-poles, Isotrons, aluminum tape on the windows, ad infinitum, and at one locatio
Most of these posts tell us more about ourselves than about the antennas. We all are potential suckers for a "seductive simplification". We want to sort things out and not have to keep analyzing them
Possible explanations: 1) These guys aren't hearing them either - they are re-posting stuff they see on eHam or DX Summit. 2) They have much, much better antennas and/or locations than you do. I reme
FYI the higher wind rating versions, with larger, stiffer tubing, are less prone to this. 73 John N5CQ -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk@contesting.co
Sometimes 10 feet can make a difference. My property lies across two counties. County one: Requires full "limited development permit" complete with wet sealed engineering drawings and information she
I doubt you would have much success devising some kind of "brush assembly" to ground those top sections. I would ground the coax shield to the tower at the top and bottom and use the Polyphasers as y
Doc it works great but it is expensive compared to clamps. You have to get the surfaces really clean and follow instructions carefully - but if you do the results are very good. I went with the compr
Best thing to do is model over your terrain. My experience is that best triband compromise spacing between 27 and 30 feet. Final spacing usually dictated by mechanical issues. With more than 30' spac
75' is a little low for optimum performance for 40M DX, but it will sure beat the heck out a sloper. I would look at the new force 12 40M elements that are 85% of full length. I do know if they have
My test was "well out of reach of a teenager standing on top of his pickup". I decided on this test after my neighbor reported seeing a truckload of teenagers hop over the fence at my remote site one
The LMR400 will not hold up well in that application. Since the loop is short and a small fraction of the overall attenuation along the feed line, I use a mechanically strong coax that can hold up. I
The city is not "required to okay any height you need", and if you take that attitude with them you may be tied up in red tape for a while. But, in Texas they are required to "reasonably accommodate"
It depends on the soil. In alkaline soils, copper clad is fine. In acidic soils, especially when wet most of the time, steel and copper clad may not last, and some people have recommended galvanized
I have some of both but would use BuryFlex throughout next time. 73 John N5CQ I want a low-loss coax to pull into my buried conduit and am looking at the Davis BuryFlex vs. LMR-400. Apparently the Bu
The spacing between the towers is an important parameter and I could not tell from your post how far apart they will be. I use a rule of thumb that if the towers are more than 80' apart, they are ess
I don't think tying anything together that is more than 80' apart does anything, because I believe the energy from the stroke will go somewhere else quickly, rather than patiently traveling out the e
Many years ago I had a 2 el quad and a TA33 tri bander at the same QTH. Quad was much quieter during rain showers, and a little bit quieter the rest of the time. Quad also required lots of repairs, a
