Yes, you are absolutely right. My memory is failing. Cebik exists and wrote on other matters as you no doubt know. Sevick of course, is the balun guru. Sorry for the confusion...sheesh. 73 de Gary, A
In further amplification, L.B. Cebik was an unbelievable antenna guru, and as many know, has recently gone sk. A great loss. That's why his name was at the tip of my tongue. Sevick is the man when it
The coax shield is like a water pipe. It has an inside diameter, and surface, and an outside diameter, and another surface. The inside surface carries (or is supposed to carry except for imbalance) a
In the real world this doesn't often happen. I run legal limit out here, and none of my several neighbors have TVI. They have, variously, VHF old fashioned TV antennas, or older C band satellite ante
Hi Ron, Not sure what your point is. I guess maybe you just did not care for my writing style. No, I'm not young. I wish I were. Old fashioned in this context meant that as far as television viewing
CW....is that the funny beeping sound ? I have a filter for that.... Now, kidding aside, I think its a great feature. Nope, I don't need it either. But I love it. 73 de Gary, AA2IZ majority of the ch
I use two, and its probably overkill. I use one before the linear, and then I use one that comes after the antenna tuner (and linear). I'd guess I get very little additional bang for the buck that wa
That is correct. My antennas are all resonant, and cut right close (or adjusted right close) to where I generally work in the band. In addition, the impedance of my antennas at resonance is very clos
Unfortunately for us all, many linear amplifiers have some gain at VHF frequencies. In fact, much has been written about the idea that gain at VHF frequencies can cause runaway "glitches" in linears,
Actually, you might enjoy reading the History of Electronic Warfare (written for the AOC) which gives tons of insight into radio and radar development in the early 1940's. Those guys were very aware
That's right Ron. The whole point of my post was that the RF we care about is NOT a problem. Here is a snip from my post.... ......That said, the RF we have been talking about, especially at HF, is i
Hi Carter, I am referring to RF that is MUCH higher than anything we use as hams. There is Controversy about exactly what frequency is the threshold above which it is ionizing. All are agreed that fr
To me this whole parasitic issue is very nerve wracking. This issue seems to be that absolutely no one can say what triggers it with certainty, nor do people agree on the fix. Obviously ham radio man
In my case I have a very low noise level, a tower, a big beam, good ground, up on a hill, and so forth. I can "hear" better usually than the other guy can. So, if I run my amp, I can often compensate
