Like you say this cst plot shows near field, its what happens in the far field of an antenna which really matters, and how the radiation from radiator and basket combine in the distance,and no plot is going to show that unless you got a 75 mile wide screen monitor, which given the present state of electronics is unlikely, so we can only assume the view Donald/Sirio has supplied does exactly that in the far field knowing it outperms all others without exception yet at those sort of distances.
@ Eddie, how do you know the guy in Europe who tested the antenna knows anything about antennas? has even got a clue how to solder properly?,isn't testing in a valley,which where i live has significant effect on any antennas radiation pattern, you will always perform better line of sight here up and down the valley than you will to either side where the hills exceede in many places 300m asl.
i have no idea who the guy in europe your reffering to is, but i have spoke extensively in the past with Donald by pm and through many threads on this forum and have ABSOLUTELY no doubts about his credentials or knowledge, what is this mystery Europeans credentials?
If Sirio listen to Donald which i know they do, then why does so many people on here doubt him? Sirio are no mugs and they certainly wouldn't listen to anyone who didn't bring something positive to the table, of that I have no doubt.
any mug can do a review, but actually understanding,describing,relating what they are seeing is wide open to misinterpretation and misunderstanding.
the first ever post Donald brought to this forum, Bob 85 and i spoke by pm or paltalk can't remember which, but Bob had previously shown me Donald's website and products, i told Bob right away and i'm certain he will confirm this, that guy who just posted is the guy who makes those antennas you showed me, Bob wasn't sure, i said pm him and find out, i was bang on. despite knowing nothing about Donald i knew who he was in one post, knowledge like his is rare and stands out a mile. I might not know as much as Donald, but I do know instinctively when someone is brighter than me.
I still find it hard to believe that you guys still debate with the only person ever to prove by cst that everyone else (except Bob and a handful of others) who said it was a j pole with non radiating basket were WRONG. He's proved the basket does indeed radiate in phase with the main radiator, where everyone else said it didn't radiate at all with a handfull of exceptions. the great Masterchief the biggest promoter of this wrong assumption, no longer shows here, WHY IS THAT?
what happens in the far field we can only assume, but countless tests in many areas and from many people always come to the same conclusion, in the far field the sirio vector 4000/avanti sigma 4 it was improved upon from, both have something happens in the far field that make them see a much further transmitted signal than conventional 1/4,1/2 or 5/8 waves, i wont even mention .64 waves as to me that is nothing but snake oil and even if it was true would be nigh on immeasurable, what happens on these antennas is measurable by the simple fact that switching from any verticle to sigma 4/vector 4000 gives you more chance of being heard with a better signal at extreme range, of that in my mind, there is no doubt.
i'm not saying they are the best skywave antenna ever, as that is nigh on impossible to prove as its mainly down to conditions and i've seen 1/4 wave gp's,1/2 and 5/8 waves outperform beams mounted on same mast many times, but when it comes to extreme line of sight antennas, i've only ever seen one, and so has Bob that gave the sigma 4 a run for its money, that was a ham international big mac and theres not many of them left to do direct comparisons tests due to their pish poor construction and many weak points, not to mention severe weather that batters northern europe frequently where most were sold.
