Another economical and light weight method of pushing wire through brush would be to use a 10' piece of 1/2" PVC or plastic electrical conduit. In the case of the electrical conduit it can be extende
To be or not to be--TO BURY OR NOT TO BURY--that is the question..................................IMHO of 34 years playing with antennas, it has been my experience to use NON-BURIED Radials as I am a
In addition to what Frank has written, I suggest that you study this link for ideas. http://k9yc.com/160MPacificon.pdf FWIW, I heard you pretty solidly every time I tuned the band for an S&P run duri
Hello fellow Topbanders! Had lots of fun in the Stew, thanks for the contacts everyone! Looking forward to the CQ160 and as always trying to find a way to improve antenna performance.... so looking f
Here's how I lay radials in the woods with heavy brush. I have a ~15 foot long piece of wooden oak stairway handrail. The kind you see for basement stairs. It's about 2 inches in diameter and has a f
Dear Eric (and Carl), I really enjoyed your piece - it was the most enlightening piece I have read about ground systems in my entire time on this reflector. Phil K5PC's response was similarly thought
Yes I can concur that you were a pretty solid signal here in Europe during the Stew Perry Contest Dan ! 73 Roger G3YRO _________________ Searchable Archives: http://www.contesting.com/_topband - Topb
Short version: Anyone who has four elevated radials can easily check this out. How to in Long Version. 1/4 wave elevated radials can have 18-60 ohms ground induction loss per radial. Divide by number
In regard to pinning them on top of the ground, I use bobby pins that women use to hold their hair in place. I go through thousands so cutting wire up got old a long time ago. It will depends on the
Gentlemen: No one will be forced to take discussions of 160 meter content off this reflector as long as they are carried on in a civil manner, without personal insults, taunts and innuendos. I have Z
Eddie, Great Job! I would not worry to take results any further unless an individual request. Your results are a helpful visual, resulting in the fact that indeed you can obtain increased DB's as a r
I'll try to keep this concise. My assumption in this is that you want to do as well as possible with the least loss possible. If instead, you are past dealing with lots of mechanics and that's why yo
HI, Grant! A couple of things to think of. First, as reported in the IEEE paper mentioned earlier, increasing the number of elevated radials to more than four , yields a rather limited benefit, This
Sounds like really effective approaches! I expect that the narrowing of the BW as you added radials was because the additional radials were reducing the losses of the system and therefore raising the
Hi Tom, thanx for the well-considered reply. Oops, I wasn't clear enough. I was referring to a reference 1/4 wave radiator. The point was that folding over portions of it to make an Inverted L, which
Hi Wes, Thanks for posting up the Severns material. I had started looking for that, but without memory of exact words (which makes searching difficult), and without absolute certainty that Rudy was w
Well, not so quick. High end academic research on radials and related ground interactions effectively ceased in the 1940's when commercial broadcasting got their solution in FCC standards for commerc
I recall a discussion on here some years ago which proposed that, whilst being an amazing antenna for top band, if you could achieve it, the broadcast model was not necessarily the best use of resour
