Bob, here are some overlays of several vertical CB antennas of note...that I compared. Here again, the (*) beside the antenna model's title indicates the active model. I did not verify each model against a Free Space model, perse, but all of the models are dated here, and during this time I was making sure my models had a good Average Gain result in Free Space...before setting the model to Real World with losses added.

Here again, we see very little performance differences...something I've claimed for years...that I was seeing in my real world comparison work on some of these same antennas, albeit my ideas of A - B testing were considered by most experts here...as no-way-no.

Bob, these overlays show us again that you are right...the Vector shows the most gain. All models are at 36' feet to the feed point.

Personally, I'm not sure anybody has ever been convinced by these models, but I think modeling has dispelled some old CBBS ideas of the past.
