AudioShockwav: The function of forum, comment, and discuss radios, antennas and technology. Users assigned to the antennas fantastic properties, are the ones to try. It is not my case, I deny these fanciful or commercial intent properties. In the case of V4000, the Dominator, all "tests" are...

When you start to accept for valid, erroneous data, no wonder then assigned fantastic properties to real objects. "Dominator is a co-lineal antenna" :LOL:

MY EXISTING ANTENNA 11 meters. It is a picture just "cubes quad" fed into the vertical side for a lower irradiation angle. After installed as square, I reformed by changing the form to get an even lower angle, making trapezoidal. This is optimal, and have made many DX to Europe, Central America...

Actual concepts of the antenna have very clear, The V-4000 antenna, "Dominator" or whatever you call it, is only a Zeppelin antenna(J-pole) and nothing more, just a crazy mind can come up which is co-linear. I leave the fantasy for others. saludos!!

Hello, I would look for resonance boxes with GRID-DIP, only tool that can tell us the real resonance. The problem is that changing the resonance of some changes the other by proximity. As for the parasitic elements, are given more importance than they actually have. These add little after the...

And we waited so, so long ..

Helo !!

"I do not know pc" :whistle:, but I see that many here know nothing about radio, no antenna, transmission lines, and impedance adapters. They should start doing school here. Antenna Notes

If you can prove something with a diagram of a software U $ S 2,500, no need to make a drawing hand, but like you can not prove anything scientifically, marinated published drawings of many words, never proven by scientific evidence. Only drawings and words of the cheapest car salesman.

Yea! Brain!! I already got the cone of the antenna SIGMA 4 radiate in phase!!

yes..You have reason Mr... like this? You know very well where this drawing is handmade "proof" of the antenna efficiency. Sure the CST STUDIO SUITE® software did for you!!:D

To add to this and not repeat it, you see that the performance of the antenna in question is well below 50%, and this image has already been published previously. If you have something better, I would like to see it published, because I only see drawings and thousands of car salesman...

I'm talking about antenna engineering, engineering transmision lines, and you're talking about amateur radio, a "one boy told me." If you want to continue to be guided by what they say and do not try to figure out on their own, will continue to believe the same fantasies. "Antenna impedance...

You failed miserably to once again I'm not putting to argue with someone who ignores an impedance adapter is an attenuator, and still ensures that it is not. Continue studying.

Incredible, there are people who do not even know the websearcher, and who can not write "impedance matching" in their search online. If they take time to study, then no fools would pass. Attenuator calculators - PI and T | SiversIMA I'm going to milk my cow in Argentina pampa.

Henry HPSD And you know that the swiss quad? On the other hand brings the case what someone said about the antenna, reviews spins in the air. A Swiss quad could not compare with the cubical quad, are very different. The swiss quad has two loops in the same place at ground potential. The...

The best quad antenna is a SWISS QUAD. It needs no insulation, or reeds, or anything, is all welded to the mast!!! I and 2 are constructed for years and am about to do a third. Broke down because they did absolutely iron pipe plate for electrical connections. The gain and directionality when...

As we say in "Spanish" (Castilian language truly, in Spain they speak at least 6 languages) , --"se quemaron los papeles"--"papers were burned" Matching the impedances isn't particularly efficient: it actually gives a 6dB loss in a ideal circuit. In a REAL WORLD is much more.:whistle: CST...
