It wasnt meant as an ignorant comment so stop trying to start trouble; this has been a very nice forum.... I know many Russians personally and have had them at my home as well as been to theirs if in
Why do you feel it is the best? Without knowing the circuit of the limiter I can just surmise that it uses diodes or other non linear device to clip the input above a certain level. Try it ahead of t
I understand the process quite well but I dont understand the need for such a device on a Beverage the large majority of the time. The only time Ive used a preamp is on those quietest of nights where
"He clearly said he has an 8 circle array, not a Beverage." Yes, John reminded me of that a day ago. So when are you going to publish the schematic and parts list for that preamp that you use? Many o
Lucky me there is no "HOA" where I live. Mention HOA and everybody says "huh? No way". I am about 4000 feet from the nearest runway but that is for small aircraft and the 4000 feet is from my home to
There has been a private grass strip at the farm that stretches about 250 acres from directly behind me to almost 3/4 miles down the road. When I first put up the 160' tower which is about 450' from
Id like to think that many of the OT's that worked the band under the old power restrictions found many suitable small lot antennas. A look thru the old QST's, CQ, Radio, HRM, etc likely will show a
It would be interesting to compare the FCP against a wire mesh on the ground at the base to 30-50' out in 4-5 spokes as Ive described several times. That made all the difference in the world when 60
This is what USN radio patch panels looked like from WW2 at least into the 60's. Very reliable, however finding one or even the parts to use might be a bit hard. http://www.virhistory.com/navy/ships/
I never take anything for granted when accuracy is desired. I use a noise bridge and my receiver to zero in on the exact frequency, the noise backround null is very pronounced with good coax. Beats t
While Im not in a high lightning area we do get some beauties plus Im on top of an exposed hill. The #18 insulated and stranded used on the old Beverages was fine when removed after 20 years and reus

In the early 60's I had a full size 40M vertical on top of a 70' pine tree with a bunch ....maybe 8-10...of radials tossed over the branches and weighted with lead fishing sinkers. It was a superb DX
I run a 500' BOG that shows excellent directivity and sure doesnt need a preamp. Velocity factor is determined by the ground beneath it and since mine is over rock only 8-24" down it might as well be
I got the idea of the mesh at work from a Tech Class engineer but dont remember him referencing HRM. This was in the mid 80's and I was complaining about the poor performance of a shunt fed 100' towe
I wonder.....Is there is a simple way to compare the field strength of an FCP with my current NON dense and uniform ground system, and draw reasonably accurate conclusions about efficiency improvemen

Im sure chicken wire lasts longer in the great southwest but it rapidly turns to rust in the acidic soil and acid rain of the New England rust belt. I see rolls of it regularly at our trash transfer
I've used screens when I needed a wide bandwidth ground system, but never under other conditions. Adding a screen or preferably, additional short radials at the base will assist in stabilizing the re
