If you install the Firestik at 20 feet tall hat before.... You can use the tower as radiating from 5/8 and Firestik would be a ground plane.

The cone can not radiate in phase with the rest of the antenna, their currents are inverted and hence canceled. For that reason they can not show a pattern of gain in a model. If you have a model, so I do it public as public do I design models. I've published several, you publish any we serve...

An antenna does not work by itself. Support, and coaxial is a very significant influence. This is ignored by the majority, believing that the antenna works alone. Many use the Vector 4000 on a small mast, and there it can get better result than other shorter antennas that are more...

"NOSEPC" -- no se PC- is spanish, means in english "I do not know about as PC". is an irony, I started with the PC in 1988. Yo no hablo ingles, apenas lo interpreto. I do not speak English, just interpret it. Pero yo estoy en radio desde 1980. No soy novato. But I'm in radio since...

THE FREQUENCY PHASE 1/2 WAVE LENGTH in the total length of the antenna SHOWING WAVE ANIMATION, I COULD NOT APPLY TO 27 MHZ, 98 MHZ OR OF CREATION THE ANIMATION. It may be a sub-harmonic, fundamental frequency not. Only radio frequency laws are all wrong or erroneous. (or are erroneous...

"http://fmbroadcastantenna.com/dominator.html" ".. It is a high gain vertically polarized .82 wave( ?? ) Coaxial antenna. It is the coaxial cone at the base of this antenna.. " What is the coaxial wave???? .82 ?? "..It is the tapered 1/4 wave coaxial cone that sets this antenna apart from...

The absolutely wrong you are. The animation does not show a phase radiation, but that looks like the current travels 180 ° In the animation the animation erased degrees of phase. Why? CST modeling shows. http://fmbroadcastantenna.com/dominator.html Then make a comparison on anything...

I find no point of parallelism between an OPEN SLEEVE antenna and Vector 4000. I would like to know where you come and explain it. <gotproof> http://www.mydarc.de/dk7zb/Duoband/open-sleeve.htm. I found a page where irradiation show an animated diagram CST?? :thumbup: Looks perfectly...

Anyone who knows a little about antennas, you know that for the next segment of antenna phase radiate in the same direction and phase must be 180 degrees out of phase. As it does? Magically gives a flip in the air? The rest is fantasy, I have not seen a shred of evidence other than a drawing.

The question is very interesting. It is very difficult to give a correct answer. But if the tower contributes, the results can be surprising, and far exceed supposedly more powerful antennas. Assume that the tower is not radiating at any vertical antenna system suited to them, is fantasy...

Reginald Fessenden - Wikipedia, the free encyclopedia "Because the J-pole and Zepp are electrically identical in function, and are similar to all other end-fed antennas in problems, pages on J-poles, Zepps, and end-fed verticals overlap." W8JI From my point of view, the Vector 4000 is an...

From my point of view, the Vector 4000 is an antenna Zeppellin. (Or J-pole invented according to denomination now) It is a half-wave radiant + fourth wave of adaptation. Nothing more. The fourth wave can not radiate because the currents is canceled by parallel skirt. The antenna does not...

Sure you know for what reason one j-pole is not a Zeppelin ?? explain it!! :thumbup:

You should be aware that this tower, radio and everything is also metal antenna. When you apply radio frequency to an item, do all partners. If you do not believe me, just do a simple test. Put electric current in coaxial cable, and then go and measure the antenna to see where in no current...

Then we agree that free-space models are not very useful. We agree that the manufacturer indicates 2 dB (4.15 dBi) over a dipole. I think you are a user and an advocate of the Vector 4000.?? Then you have models that I provide for comparison?? You have models that we use in our...

If THE ANTENNA VECTOR 4000 was as good If you like says, their manufacturers, advertising with us obliterates radiation diagrams, ........ ....but it is that they are non-existent, not seen anywhere, not published anywhere, not are. : Confundido: I have not seen anywhere radiation diagram of...

A model shown landless true, perfect, imperfect, not including a mast, it sets an example for all, an antenna does not work in a vacuum. An antenna works with real magnetic fields. To say that a SIRIO Vector 4000 focuses more energy on the distant horizon, is very quick, perhaps you could say...

SIRIO the extension to 7/8 and got nothing :laugh: NO LONGER IS BETTER. :laugh: now returned to the measures listed AVANTI!! :whistle:

SIRIO V 4000 "Gain: 2 dBd, 4.15 dBi" http://www.cbtricks.com/ant_manuals/avanti/av101/ad/index.htm ASTROPLANE 4,46 DB........ SIRIO V 4000 It's not new, it's very old AVANTI AV174 :bdh: http://cbtricks.com/ant_manuals/avanti/av174/graphics/sigma4_av174_om.pdf NOSEPC

not fully understand your questions Marconi. I explain. I first drawing the line source in "Geometry Edit" in X Z mode.. AC source is fed poles and obviously do not need more, that's radiofrecuency. Do not need to draw a fountain with two separate poles. That's not a car battery;..... is an...
