Marconi, want to talk about an anomaly? How about you cannot build a working Vector with an extra 1/2 wave element on top using EZNEC NO MATTER WHAT YOU DO??? No offense but you talk about how I only have words to back my findings but the reality is I have 15 years of field testing to confirm how the Vector works while you've been posting an inaccurate opinion for nearly as long.

 

Endless hours have been spent explain to you that A PAIR OF CURRENTS ARE ON THE CONE. NOT ONE CURRENT. You go back to the model that can't demonstrate anything about how the antenna works in every case as if it defends your ideas. No kidding? Of course it agrees with your idea. The problems is both you and EZNEC have misidentified an important current that will prevent you from seeing the model results in field tests every time.

 

What part of your idea not working in any field test do you not understand? Does it not set alarm bells off in your head that a 180 degree phase delay cannot be used in a collinear model or is that just another anomaly too? Notice all of these hard to explain anomalies all relate to a difference in phase of 90 degrees? When you see a 1/2 wave current shape on a 1/4 wave element, don't assume you know more than CST and it must be wrong.

 

Ask yourself why until you realize it can only be possible when two currents are on the same element and separated by 90 degrees in phase. You have based all of your opinions of this design on a faulty model and one field test with a Targa and another antenna set up at the same time. I have formed a factual analysis of the radiation currents by experimenting with the phase shift required to stack another 1/2 wave constructively.
