We deal with sinusoidal waves because all other shapes can be nade from combinations of these. The 3rd edition of Kraus` "Antennas" says on page 904: "They (computer program designers) could develop software to simulate the performance of antennas. In general, these techniques either numerically solve Maxwell`s equations by descretizing the problem using integral techniques, such as Moment Methods (MoM) as discussed in Sec.14-11, or differential technuques, such as finite elements or finite difference-time domain." Maxwell gave us everything we need. Best regards, Richard Harrison, KB5WZI Richard you have not come up with anything that contradicts what I have apothosized, nothing ! \When I mention antannas of a new desighn you say who needs them. When I say that antennas should be tilted with respect to the Earth you say BS. When I point to the coirrelatioin between Gaus statics and Maxwell you remain silent. Now you bring up Kraus by quoting what he said with respect to computor programs. I was not happy with computor programs because of the assumption that they has about sino soidal current. My studies prove that I was wrong in that determination. This allows me to review Kraus antennas to see where he deviated from Maxwell. You point to a computor program on antennas. Most if not all hams foicus on planar designs where current is induced progressively from one element to another in simple electromagnetic coupling form, that relationship does not supply anything with respect to radiation. Programmers put that design as an addition to the program that revolved around Maxwell you did not work around approximations. Now I feel it is legitamate to apply the computor programs to my deductions and Maxwell produces the antenna that I forcast and not the lesser efficient yagi antenna.Same goes for Krauss's work on the helix which like the plana designs are also a approximation. These fact are indisputable if you believe the MOM methods used for computor programs. Now we have the situation where a yagi or the helix is pushed aside by the computor programs in favor of what I have postulated. Now it is YOU who have a problem. I kn ow you do not use computors but it was you that brought the subject up.Computor programs duplicate what I am postilating with more efficient antennas and yet you put computors forward to repudiate what I say. So what are you going to do now? study computor programming to see how a program based around Maxwellk could provide such incorrect answers, deny the teachings of Maxwell or deny the viability of antenna computor programs which puts ham radio back a generation?

No. *You* have the problem, not ham radio as a group. Antenna computor programs that have entered ham radio with the full acceptance of it's members which takes up a considerable portion of antenna news does NOT provide planar antennas as the most efficient antennas based on the compliance with Maxwell. I don't fully accept *all* results obtained through the use of antenna programs. There are a few cases where the programs have problems. Fortunately, most of these are known, and if you really understand what you are trying to model, it's usually fairly obvious if something is in error. This is no small matter for ham radio. We can bury our heads in the sand or we can re examine the facts as accepted by science. Be my guest. It's a free world. But don't feed me a turd and call it a steak. I can tell the difference in most cases. If adherence to Maxwells laws provides radiuators that are more efficient and smaller than the status quo we can ignore it as Richards states " we already have a design " or "who needs it" But so far you have been unable to do this. You seem to think that a free lunch is hiding somewhere. I'm here to tell you that you will likely starve to death before you find it. Why? Because there is no free lunch. Now I have shared my findings based on the laws of Maxwell as to why this is, you need not agree with it but surely for those who are inquisitive about antennas should be curious about the parodox that I have exposed. You haven't exposed anything except a bunch of baffle gab. There are smarter people on this newsgroup whome I have brought this to their attention so why the silence and the abuse with respect to these findings that Einstein pursued in a fruitless effort? Well, obviously they don't seem to agree with your theories. And who could blame them when the only "proof" offered is conjured up baffle gab. The ball is totally in your court. Either do the testing and prove your theory, or accept the failure. I know I'm not going to do any work on it. I don't like compromised inefficient antennas. So there is no incentive whatsoever for me to waste my energy on it when it's sure to be less effective than what I use at present. |

Richard says: Hooray! Richard does not discourage novelty or the computer which is a most useful tool. Show us the novelty and the data. Art`s rant reminds me of an offhand remark by Jerry Chinski, Chief Engineer of KXYZ when I worked there in 1949. It was not directed at me when Jerry said: "You can have the best equipment in the world but if knuckleheads are operating it, the product is likely useless." Antenna modeling is well tested and accepted. If the computer operator is a knucklehead, its output is likely useless (GIGO). The operator likely needs help to get useful output. But, some operators blame the system not their own ineptitude. Many participants in this newsgroup use EZNEC to get good results when evaluating prospective antennas. I`m sure some blame the system when it doesn`t produce the desired results. I`d call them Chinski-ites. My 20th edition of "The ARRL Antenna Book" includes a CD-ROM of the entire book. Chapter 8 is "Phased Array Techniques" , written by the EZNEC man, Roy W. Lewallen, W7EL. It is full of practical information in print for all to see and criticize. Last line in the book is: We would appreciate any feedback or bug reports you might have. If Art would subject his data to such scrutiny, he might get more cheers and fewer jeers. Best regards, Richard Harrison, KB5WZI |

There are many experts and guru's on this newsgroup who pretty much agree with you and not one has come forward to refute some of the things that have been stated against what I proffer So I will assume that the program is accepted for Yagi' but not for radiators in equilibrium.

Those who do not understand the rules of science with respect to radiators say it is bafflegab because they don't understand the sciences.

You sound like today's concession speach as a warm up for the next campaign cycle.

Ok Richard so I am inept, let us leave it at that. There are many experts and guru's on this newsgroup who pretty much agree with you and not one has come forward to refute some of the things that have been stated against what I proffer I refute things you say quite often, but you ignore them. As an example, you constantly state that an antenna should be a full wave length in order to live a productive and useful life. You claim such an antenna is in equilibrium. Whatever that is supposed to mean to you. We don't know how equilibrium applies in your case, as you refuse to tell anyone when questioned. When I state that a full wave has no real efficiency advantage vs a half wave, a statement which almost everyone knows is true, you ignore it. Of course, using a small antenna the size of two shoe boxes is not really a full wave antenna. It's still a very small antenna fed with a loading coil made up of a full wave length of wire, if I understand what you are doing. And with your winding technique, it's quite easy to see how this could be a very lossy method to feed such a small radiator. You basically have a dummy load on a stick. A good 160m mobile antenna setup would tear it a new one.. :/ So I will assume that the program is accepted for Yagi' but not for radiators in equilibrium. How can a radiator be in equilibrium? You are talking about a piece of metal. All this is not unusual a lot of things that were found out were delayed from the public because of people just couldn';t take change. Change... Hummm.. A common Obama mantra.. Change can be good, or change can be bad. Throwing a lot of the Wall Street CEO's in prison would be a fairly good change. A new president who thinks he can bend the constitution to suit his personal agenda would not be a good change. Ignoring proven data and replacing it with faulty unproven data would not be a good change. Using proven data and building on it to prove a new design or theory would not be a bad change, if the new design or theory can pass the scrutiny of rigorous testing over a period of time. Using conjured up baffle gab to try to prove a new theory is not going to cut it in the change dept. BTW, I mention Obama quite a bit, and it's probably no secret I'm no fan of his. But I want to mention it is not on a personal level, or due to his skin color, etc. I'm sure he can be a fairly decent guy at times, but I still think he's a blatant socialist, and I have little use for him. He's a constitutional attorney who has no respect for the constitution. IE: he'd like to take a big crap on the 2nd amendment if he ever gets the chance for just one example. This is not to say I really like McCain either.. I'm more of the independent Libertarian ilk.. If a politician can't follow the constitution, I have zero use for them. But back to the matter at hand.. Those who do not understand the rules of science with respect to radiators say it is bafflegab because they don't understand the sciences. I understand enough to tell a turd from a diamond any day. An Einstein level of reasoning is not required for this simple task. So I will let it go at that and assume that I am the one out of step. You have taken the first step towards recovery. You and others have made your point and there is no such thing than a better antenna than the Yagi and that all is known is about antennas and nothing that is not printed in a book is acceptable to radio hams. I get the message and that should make every one happy Just more whining from a disenchanted pseudo inventer.. I don't even know how the poor Yagi got involved. The yagi has zero to do with anything I have argued about. A contra wound dummy load on a stick, and a yagi and about as different animals as chipmunks and baboons. Or are you know abandoning the dummy load on a stick, and returning to the perverted array with skewed elements you harped on quite a few months ago? You know, the one that provided less performance than the properly designed yagi with an equal number of elements.. You know, the one I called the cluster%#&* antenna.. Chortle.. :/ |

The ARRL Antenna Book has an interesting section on "Short Antennas" that starts on on page 6-21 in my 20th edition. On page 6-30 it says: "Loading is always a compromise; the best method is determined by the amount of space available and the band(s) to be worked. The simplest way to shorten a dipole is shown in Fig 53. If you do not have sufficient length between supports, simply hang as much of the center of the antenna as possible between the supports and let the ends hang down.
