I am begining to believe that there is really no interest in small antennas I use small antennas all the time. So is there really somebody being hired to produce small antennas? It would be fairly hard to use a small antenna if no one were around to make any... :/ Same situation with hams as they fight at the very idea of the possibility of small efficient antennas that like the Universities do not want to hear of the possibilities Most that deal with small antennas eventually find that there is no free lunch. This attempt at small antenna perfection has gone on since way before I was born. Of course, being that you disregard all previous science, I guess you missed the memo. ![]() One doctorial student at Illinois University in Central illinois stated that they have so many requests for review of antennas by the populace it is not unusual to ignore the pleas of the local populace presumably based on the premise that if it was possible they would already have done it. And he is right. They have only had about 100 years to work on it. They have teachers way more intelligent than ordinary peopleand, where one spends most of her time working on behalf of the IEEE that research or computer operation has to be put to one side. Delirious jibber jabber disregarded... If there really was an interest in diverse antennas instead of personal promotion maybe our tax dollars would be better spent. Yes, I write off the University of Illinois as they have never produced anything as pioneers in antennas especially with the departure of the log periodic designer that they paid hansomly to hang out there instead of there own Universities. And likewise, neither have you.. So where is the beef? So to sum up puting U of I to one side, is there anybody in Industry who desires small antennas or Universities investing time in such things ?. Yes. But they deal with the real world, not a bunch of conjered up voodoo science. When O when is anything going to happen in the small antenna areana or is the need actually ficticious because of diminishing returns with the use of such? You can't polish a turd and turn it into a diamond. Only people with limited room are likely to be interesting in accepting a decrease in performance, vs using full size antennas. The only place you see me using small antennas on HF is mobile. And while I've spent a good deal of time trying to optimize the efficiency of those antennas, I have no delusions of grandeur when it comes to their efficiency vs say a dipole. I happen to realize that there is no free lunch. What Universities in the U.S. that are serious about small antennas and what have they produced in the last couple of years? Why don't you ask them. Could care less myself.. If they can't or deny the possibilities then why fund them? I don't. It is your money. But then who cares, we have antennas already so we don't need anymore especiually when denial of the new suggests that all is known. Good point, and I agree. I really don't care. I like big manly efficient antennas, not air cooled dummy loads on a stick. :/ If you say all is known, I'll take your word for it. Of course, I know that's not true, but if it applies to you, it's good to know a man who knows his limitations. Clint Eastwood would be proud. ![]() |

As, when you peek closely under the hood of the NEC engine (at least the one I use and have the source code to), it does have a bit of what you call "voodoo science", IMHO ... Only people with limited room are likely to be interesting in accepting a decrease in performance, vs using full size antennas. The only place you see me using small antennas on HF Don't forget us guys who are over 50 and getting tired of maintaining large hunks of metal in the sky and fighting the force of gravity Gods to do so (in more ways than one! And, not to mention neighbors, rules, regulations, etc.) With the price of real estate being manipulated near "Hong Kong Prices" (what is that, about a million dollars a sq. ft.?), reduced size antennas will only increase in uses and demand ...

As with many of your opunions, none are supported in accomplishment and I dare say you cannot recite a block of labeled code that conforms to your supposed humility. As with your confidence in reciting the volume of a sphere (and lacking a simple answer to my offering a chord measurement to test your confidence), I can well anticipate your post here, is as much a Troll as any of the rest. You can offer that labeled block of code to support your statement or admit your post is so much babble or your post is yet another troll How many rounds will it take to resolve to one in three? I am sure most here would hammer the last two in a heartbeat and the mole would be whacked twice. 73's Richard Clark, KB7QHC |

You can hear it for yourself if you go here and type "bull@#Z$%" into the frame. http://www.r2d2translator.com/ I just asked him if his sensors felt any extra amounts of excrement applied, and he sputtered out another long tirade, which ended up meaning, "well you can see the stupid meter for yourself can't you!!"

As ... 73's Richard Clark, KB7QHC Richard: Doesn't it even embarrass you in the least to make such statements which the mere application of common sense will declare an outrageous lie(s)? The code which comes into play when a gamma match configuration of elements is defined and handed to the NEC engine, along with the proper pf to cancel the inductance of the gamma-rod, should be proof enough .... to any legitimate software engineer with "an antenna hobby." Indeed, any man with common sense who can understand the equation(s) being called to play and their very (rounding/guessing) nature ... Download the code and locate it yourself! It comes in Fortran, Basic and "C" flavors--at least ... if you are intelligent to understand this conversation on even a basic level, you should be able to accomplish that ... Regards, JS |

The author, a professor and amateur, notes that the power is not being "lost" as heat ... so you propose it is being transferred to another dimension? You remind me of the guy who took the boat trip to see the ocean. He departed on the boat upstream at a large river. No one ever bothered to tell him that he had reached the ocean ... he fell overboard ... among his last cries, was heard, "And, I did so want to see the ocean before I died ... gurrgleeee ... " Regards, JS |
