Hello Guys, Perhaps a past topic is worth reading: http://www.worldwidedx.com/threads/omni-ground-elements-effecting-a-beam-below-them.112294/ Kind regards, Henry 19DX348

Homer ! Thank you! That is what im looking for...and I was thinking...and thinking...hihi. For me it is normal to "know" that... As in "antennas" you work with those figures on regular base, in fact measurements or often done like that. Its welcomed that you didnt indicate it like that at...

1- The first table does... (it gives several dB extra compared to those others. for most due to its height of course.) 2- The second doesn't. (equal tip height no losses etc) That indicates that if "all" is done well they should be more or less equal at same tip height. If that isn't the...

Hello Homer, Yes, I do understand.... And we indeed need to focus on "what would be best". Though your question "why" it has worked better is a question for which I can not find the answer. There are so much variables. The "bottom" line is....if we illuminate all those variables and put them...

But Homer, With all due respect... Why would you think "we" are trying to duplicate your situation? Im afraid we or atleast I cant do that...we can only provide an "average" situation. It would be quite some work to really duplicate yours. There are too many variables....for your situation...

Oke, Dont think im around the weekend... ...seem im in Germany :-) Be back on Monday or so.. @ DB: Well, I really do not know if 4nec2 is oke with providing the "total thing" That is why I asked you to find out before putting things on line. I can imagine it pretty much to be so, but Im not...

@DB The graph at 30 Km is done with Pro/4. Perhaps that is confusing ? The "real" gain measurments were done at 30 wave lengths. (2 meters = 60 meter distance) Ill try to answer the rest of u tonigth...all ready 07.37 running late.... Kind regards, H>

@ Homer, Yes, for me and dB it is not difficult to understand. The questions I gave ...was not a question I had. They were an answer to why it is not used as "primairy" antenna figure ....like "freesapce gain....a kind of:"general" rule.... As for each situation all will be different, which...

@Robb Seems that Sirio has enough software and analysis equipment to backup their claims. They aren't into this game for the short run Indeed, they are not, they have been doing it for a long time allready. And If you would ask me personal...I actually like them. But as with a lot of...

@ dB... I all ready provided such a plot in the article ....showing indeed that 2 dB distant"gain" difference..Using enzec pro/4 (see article) Where all others were "optimal" We had in the beginning in this thread some talk about it ? I provided to you: The indication of the surface wave on...

which / who's raw gain figure (@ dB )? And yes, it does look better...doesnt it (y) Kind regards, H>

1.) why is there no current on the outside of the cone from the bottom of the cone as it is grounded to the rest of the antenna there, and 2.) why it is not once again a 3/4 electrical antenna given the currents inside the cone have canceled each other leaving us with a nice clean metallic...

Donald, I kindly asked without the personal things please.... Kind regards, H.

If you see it that way...your vision Donald....but I understand. Although it is not needed, I will remove that name on the site Donald As i really have no interest in making you look bad. For those interested....lets talk about antennas again ! Including you Donald...if you want... as long as...

Hello Guys, I am rather bussy...so i do miss a lot, constructing a house hihi. I didn't read all as I for most saw.:..hmm..."things". If there is a technical question...? No problem, but excuse me for not reading all the previous posts Kind regards, H> PS Donald, If it truly was my...

Hello Homer, Oke tnx for answer. Understood and in consideration :-) Kind regards, H.

I believe it is a correct assumption that Henry has rested his case for the antenna on a conclusion the matter is settled without proper testing in the far field distant horizon If I may ask...based on ? Or could it be that I actually have tested several on 2 meters for example ? A band with...

Oke.... The 30 Km thing: Well, antenna radiation always becomes weaker as soon as we have more distance. (not talking about skip conditions of course) That can be found from the "friss formula". (google.....friss transmission equation or so) What it comes down to... A signal will get weaker...

@ Homer: If I offende you in anyway...i am sorry...it was never intended that way for you. Thank you for the questions... 1.) "is this a 1/2 wave, or is it a 3/4 wave? Hmm...always difficult to give a yes or no answer... well its a 3/4 wave. 2.) If it is a 1/2 wave why does no other 1/2 wave...

Ah Donald...ah you have a point ! you are right..(how does that feel ;-)) The Name Dominator is indeed there... I did indeed mention it. That was uploaded during this thread (REMEMBER?) To show surface currents. NOW MY CLAIM WAS: I didnt mention it in my article. Please link to it again... as...
