And since a patent application is involved we're not going to see much real data for a while anyway. One point to watch for, though: What matters in practical antennas is the performance of the entire antenna system, not just the antenna itself. For example, a short (in terms of wavelength) whip antenna can be quite efficient - it's the matching network and ground system losses that reduce antenna system efficiency, and bandwidth, to low numbers. Physics is physics is physics and we all know the implications of short antennas *and* we've read the similar hype which surrounded the farcical CFA and EH antennas to name just a couple of this thing's predecessors. I'll stick with my "snap judgement", the thing is guilty until proven innocent. Maybe. Or maybe it's for-real. Without detailed info it's all academic anyway. But I remember a time when it was said that "physics" would not permit microprocessors faster than about 25 MHz. Nor with more than a few thousand transistors. Etc. Had nothing to do with "physics", had to do with musings posted by a few gloms who were clueless about how rapidly developed chip manufacturing technologies could leap past the limits of their own imaginations. Hoof. Mouf. Classic. There was also a very learned "professional in radio" who, when informed of the intent of the 1921 ARRL Transatlantic Tests, proclaimed that it was physically impossible for a kilowatt input 200 meter transmitter to be heard at that distance. Waves were just too short, doncha know. Physics wouldn't allow it. This is not 1921. 83 years later the physics of antennas has been milked to the extent that the probability of anybody inventing an antenna which does not utilize long-applied physics lies somewhere 'way out the asymptote of the curve. Per previous I'll stick. 73 de Jim, N2EY w3rv |

Hoof. Mouf. Classic. Holy Cow! PCTA refer to backward thinking people as "gloms." From this point forward, I must refer to PCTA as "CW Gloms."

Waves were just too short, doncha know. Physics wouldn't allow it. This is not 1921. As Len Anderson has pointed out repeatedly. But you didn't need him to point that out. You could see it published on the front page of any daily newspaper. Even the ARRL puts it on the front cover of QST, just prior to launching another edition of memory lane. 83 years later the physics of antennas has been milked to the extent that the probability of anybody inventing an antenna which does not utilize long-applied physics lies somewhere 'way out the asymptote of the curve. Are you sure it's not back at the inflection point? Per previous I'll stick. Ditto my opinion of the CW Gloms (previously known as PCTA). |

Subject: So Much For THAT Rant....
From: (Brian Kelly) Date: 6/9/2004 9:47 PM Central Standard Time Message-id: http://www.opengroup.com/hubooks/089/0898048044.shtml Dang near choked to death laughing, Brian! WTG! I am half tempted to just splurge and get a copy mailed to You-Know-Who and his trusty sidekick, PuppetBoy! 73 Steve, K4YZ |

I am half tempted to just splurge and get a copy mailed to You-Know-Who and his trusty sidekick, PuppetBoy! I think it was Hans who used it here originally some time ago. I knew the Putzlet would eventually provide me an appropriate opportunity to turn it loose on him so I bookmarked it. He did so I did. 73 Steve, K4YZ w3rv |

No Brainiac, not at all. In fact Chip shipped me a piece of humor-laced e-mail about a week ago. I've taken umbrage with some of his jottings here and there but I'm not into destructive posts like a certain PUTZ we know does for jollies. |

He has STATED that a "dipole is always a half wavelength." :-) You are being overly sensitive to criticsm, catapult kellie. :-) And stay away from "humor-laced e-mail." Some of it might make sense. We can't have such corruption of the CW. Beep, beep. LHA / WMD |
