And why don't you post a link to your site? Hi All, This is not going to resolve issues. I have seen enough of Art's details contributed in quotations (folks should be more selective in both quotes and focus on one point) to see he claims ALL of HF at less than 2:1 and specifically the 160M band - when he uses a tuner continuously (an odd requirement adorning the claim in the advance over conventional designs there). He also reports not hearing anything on it. The two statements easily support each other in revealing the inordinate loss due to the proximity of ground. This is nothing that hasn't been reported for years by others as they encounter the silent blessings of distributed loss. The language of Faraday shields has been corrupted to suit a fantasy, however. And Art has abandoned the arguments demanding length efficiency; and no requirement for tilting the radiator (this one is specifically described as being strictly parallel); and skewed elements (aka guss's radiators)are gone; and contra wound coils have disappeared; and what happened to paramagnetics?; and.... Well, Art's claims are like a long burning fuse that sparks for a moment leaving a trail of ash behind. The mesh burns with a sputtering flicker before it too is abandoned for the next fad when it will be discovered that the sun's particels would go through the mesh openings instead of hitting this peculiar antenna. 73's Richard Clark, KB7QHC |

I won't go so far as to say they won't "work" - whatever work is defined as, but I don't see any new ground being broken. ANother of Art's antennas, the rotatable coil on a stick is a tuned circuit on a stick, and probably functions as a EH antenna. I'd guess that most of it's radiation would be from the coax. Looking at the instructions given, I figured that's what it was going to do, so didn't take it any further. This mesh device is either a wide dipole or a somethingorother worked against ground. It will probably tune and put out a signal. I wonder how things will work as it corrodes? Might get complex. If you need to use a tuner, you might as well just put up as much number 12 THHN wire, and tune it. My doublet with an MFJ tuner works great. - 73 de Mike - |

All of you state it is a false premise which means nothing is acceptable! For my part I am dealing with known laws of physics only which is what you are rejecting.Ask any body such as a professor or anybody who teaches theoretic physics for an opinion. At the same time find out what Gauss equation in cgs units changes to when you add a time varying field! To me it is obvious that as the old timers pass on they are being replaced by operators of a hand mike who have absolutely no interest in experimentation,how a radio works or the physics background of same. Having one of the new licenses to hold a microphone does not make one an expert of any sort let alone a major in physics. Nobody but nobody has ventured forth the resulting equation or proffered anything to justify allegations of radiation from the feed line or any other scientific fact in rebuttal to what I propose. So based on your postings I can only consider you to be microphone holders with absolutely no interest in physics and only interested in the straw men that you manufacture based on untruths to which you base your arguements upon. Frankly none of you can handle the truth or change from the past. I suppose this particular thread has now come to an end as your understanding of physics results in different result from mine and you now prefer to supply insults or spamming in line with your fellow poster KB9QRZ who now appears to be using different calls to attack to hide his identity based on the content of the posts.

![]() Guys, I can't explain the antenna if you do not accept the basic premise of adding a time varying field to the law of Gauss is the same as Maxwells law for radiation. Gauss and Maxwell have nothing to do with describing the areas I mentioned. All of you state it is a false premise which means nothing is acceptable! For my part I am dealing with known laws of physics only which is what you are rejecting.Ask any body such as a professor or anybody who teaches theoretic physics for an opinion. At the same time find out what Gauss equation in cgs units changes to when you add a time varying field! The laws of physics were not questioned. I just wanted to know how you made the antenna. You are evading the issue.

Frankly none of you can handle the truth or change from the past. So, you choose to throw more insults. I suppose this particular thread has now come to an end It comes to an end because you won't supply any details. It becomes clear that you are NOT looking for any meaningful discussion. as your understanding of physics results in different result from mine and you now prefer to supply insults or spamming in line with your fellow poster KB9QRZ who now appears to be using different calls to attack to hide his identity based on the content of the posts. .... and more insulting remarks.

Your understanding of physics differs from mine. It also differs from any physics professor you would care to speak to, which is why none have shown up to support your nonsense. And differs from everyone here that has designed (that is an important word) an antenna that works as predicted. With real testable numbers and all that silly stuff. tom K0TAR |
