Even though a perfect ground, RF or otherwise, does not exist in practice, the RF ground is not a myth. At least not a myth in the same sense that Thor, Zeus, just taxes, and Chupacabra are a myth. T
I think the confusion exists because we insist on calling too many things "ground". To me, ground is earth. In electrical circuits (AC,DC,RF) there is return. I doubt the world is gonna adapt my view
This is why the electrical code (in the U.S.) is gradually moving away from the term "ground", "grounding", etc, to the term "bonding" and "bonding conductor", because it's the fact that it's a reli

That is EXACTLY the problem, Mike. We try to solve hum, buzz, and RFI problems and make antennas work better by driving ground rods, when those ground rods don't help any of those things (except, of

The misinformation contained in that post is breathtaking. The ARRL should dedicate a page on their website to that paragraph as a prime example of careless and unfounded conjecture in our hobby. It

I hope I get this correct: The word "Balun" is a contraction, or a concatenation of two abbreviations (Bal) for Balanced and (un) for unbalanced. In other words, Balanced to unbalanced. Jim's RF "cho

Yes, it's a concept. It is not reality. Again a concept. I believe you have me (W9CR) confused with KK6MC. And you're entitled to your opinion. I'm also entitled to call BS on it. -- Bryan Fields 727
OK - so besides all the name calling, mud slinging, and flame throwing, what have we accomplished???? This got boring about a week ago!! 73 Tom W7WHY I think he made a perfectly valid argument about
I was flabbergasted at the response to Duffy's post, which seemed relatively non controversial to this relatively low level scientific brain of mine. Can't one specify a perfect ground (even though i
"Specify?" I think you mean "assume." But few antennas depend upon a connection to earth for their operation (some RX antennas do). One can ASSUME a homogenous earth of known properties for the purpo
Adding a bit to K9YCs discussion, a ground plane, or any ground in a piece of equipment may indeed be at 0 volts as far as DC power is concerned, but it is also an excellent carrier for other signals
