Hello Donald, Sadly not familiary with it... Is it exactly the same as the one mentioned ? Ill try to download a manual somewhere.. Well different ways network analyzer and a spectrum analyser with tracking generator (HP) Though i also do field strength measurments, not as often though but in...

No donald, Not accurate...it is for most in that case due to height difference where the base was kept equal. In other words.. halve wave at bottom 1 wl Sigm 4 at bottom 1 wl Means higher tip of the sigma 4 primairly due to that reason in that graph the difference of 2 dB can be seen. You...

That's what I meant about Henry confusing people into thinking every other reference antenna we compare against that shows these gains is not as good as Henry's J-pole or his 1/2 wave dipole. You really think the top 3 broadcast manufactures are all making inferior center fed dipoles too? At...

Hello, Owh i didnt know that...he was aware of that. Anyway.. Donald, again... Im not saying the antenna cant outperform others. Im saying actually...it most likely will. (see article) The issue I am having is that: I do not agree with your statement about the CST plot nor the different gain...

Donald, Again you have not interpertated my findings correct. I am not saying the antenna can not have an advantage of 2 dB. You also fail to have noticed ....that the mast for example on the 1/2 wave end fed radiation plot in the article IS WITH a mast ISOLATED etc. Donald, What I Do not...

Hello All Just short ...as truly time is limited....its 0630 now...and still need coffee hihi....possible some time this evening. (constructing a house) Yes, the correct answer to the first one would have been never.... gammegatter already knew that... There always is an H field if you have...

Yes that is one... A closed loop of dc current...

I've seen more effort to "explain things away" than to explain anything at all. I tried to remain optimistic that we might learn something constructive in this report but against this constant barrage of suggesting what we see is not what we see, not accurate, not for the reasons we think...

I recognize a 1/2 wave directly over a 1/4 wave doesn't produce 2dbd by itself. Great ! So that 5,15 dBI figure and all statements with "equal to 2 stacked dipoles" etc will be removed from you site .... @ Homer... You see a lot of contradictions. All i have told is the truth. please explain...

Donald.. are most likely not the complete result of collinear action We are almost there...Im proud of you thumbs up ! ps...and yes....but the sad thing is... as soon as we have "radiation" from the cone....the antenna will become more a 3/4 wave radiator. providing higher gain...but...

PS: I'm still boggled by the "theory" that one length of mast can produce a 2dbd gain but no other multiple of mast length can detract from the gain? That doesn't even come close to making a bit of sense and sounds like you're talking out of both sides of your mouth to me. Donald...saying that...

Hello Donald. wheter or not it is 3..4..5 ..6 etc.. It doesnt really matter, eventually the density will be so tight it will become a "shielded line" (coax) If you have a open transmission line (lint line) You will have two currents.. You will have two Magnetic H fields And they will be...

Owh and almost forgot... But i dont think ill be around tomorrow...possible Thursday evening again (evening here is your time now) So, please find "faults"...or please ask a questions for verification Or please start explaining your claims besides your interpretation of the CST plot. Thank you...

But I already did Donald. You seem to have stop reading it, if you could be so kind and read it.. You will find that it is actually not "my" theory...but it is antenna theory. Now, I will answer any question you have...but I ask you to read it...as apparently you havnt. I encourage you to find...

Donald, Last time, could you.... Please stop making non productive remarks which are trying to put me or anyone else in a bad spot light for which you have no right to do so. Please remain with facts instead of assumptions. Kind regards, Henry.

Donald.. We dont disagree there are more than one currents active... There is a whole bunch of them ! I disagree with : 1- collinear 2- explination on your website 3-Gain figure provided. 4- etc. But not the different currents... And eznec is perfectly capable of providing the sum of them.

1- No....Remember ....think.... You have current going up in the main radiator. You have current going down in the radials. Apply the right hand rule. You will see that the DIRECTION OF THOSE CURRENTS near the main radiator are equal en hence the enforced density. (As explained in my article)...

Yes you can change distance and "readings" and altitude etc. But I also have seen some results that worried me, that's why I didn't provided it in first place but asked to hold on till I had confirmation. The issue is not you Db, and if you do have something ...just ask... I know you learn fast...

1- I do not understand what you indicate with "1/4 wave radiator produce a field in the shape of a 1/2 wave arc... Could you explain ? (ps picture or so will help) 2-There is ALWAYS a magnetic H field around a conductor with a travelling current. (o well...not always of course ...but in case of...

Db, of course what i say is true :) I did not say you can not talk with someone behind something.... Thats why i put in that blue not straigth line....there are things as "groundwave / surface wave / refelcted wave etc. Now, what you are doing is looking at the skywave. You are looking at a...
