Hi Bill, I sure agree with Earl, Don and Herb.....but I would stay away from Quarterwave radials. It's almost impossible to get more than one of them to carry any significant current. Try four eightw
Referring to the K5IU paper on unequal currents in elevated radials, I was surprised and intrigued when Tom, W8JI, commented that: Reviewing the material, it seems to have a great deal of merit, base
Hi Les & Others, As my name and call have been dragged thru this thread several times, I feel like I'm a part of it. I'd like to comment. The main topic seems to be effectiveness or loss especially r
Well, if that were the case, how is it that the voltage rises so much from the bottom of the loading coil to the top? If the current is the same, that would mean that power is being created in the co
Hello again antenna fans out there in radio land! In our last episode, our hero was set upon by his nemesis, that dastardly villain from the deep......sorry, just kidding, it's not like that at all.
I think you have a syntax problem in that sentence, but I recognize the formula. You said further: I think you have that right. Sounds correct to me, but what's your point? If you are alluding to mea
Well Mike, Any 20" long coil that we used would have already been closewound and would have been for 160 or 75 if it had bigger wire. So to change it to a 5" long coil with the same inductance, we wo
Openings to Europe are few and far between here in the south tip of TX. When I lived in No. Illinois I was envious of New England and the eastern seaboard. In the last 13 years I've added most of the
There's been a thread on the Reflector concerning working DX on 160 with less than optimum resources. Some folks seem disheartened faced with the successes of the "Big Guns." I don't think they shoul
I have seen references here, in QST, and on "Ham Links" about power capable rf filters with great specs (and prices) from "Industrial Communications Engineers" in Indianapolis. I can't seem to get th
Guessing at the number of turns in an air wound choke isn't necessary. Calculating the size is easy. Whether a choke is wire-wound (cored or air), coaxial wound, or "beaded", it should have a reactan
When we were looking at properties here in the Lower Rio Grande Valley 12 years ago, we used our own vehicle to go to each site (much to the disappointment of the realtors) because we had an extensiv

<Does anyone else have interesting info to share on this subject? <73, John W1FV Hi John, Although it wasn't as tough as the East Coast had it, I remember how hard it was to work the JA's in the earl
Hi Bob, As a 13 year old high school freshman in 1954, I found myself on 160 because the homebrew rig I had wouldn't oscillate above 75 meters and that band was full of AM kilowatts. Trouble was, my
Yes, and he's a great host, too. I first worked him as PY1MGF in '71, and later that year as PY1DVG. He was always in there and I got a chance to see why. In 1978 I was working in Brazil where my co
On a weekly 20m sked early Sunday eve, a buddy in Illinois mentioned the heavy aurora going on. After supper at about 0200 I wandered into the rig and tuned accross 160. I happened accross Tom, W8JI
Yesterday morning from about 1030z to 1040z I was listening to Herb, KV4FZ call "CQJA" as he is wont to do at about his sunrise. Herb was particularly strong when I tuned on him, but I noted that on
