Do you know if Avanti ever built a ground plane named the Penetrator that used a collapsed vertical trombone type feeder? The only other antenna I have ever seen using this type of feeder in any postions is Jays, and the Mosley CB ground plane antenna and they are both horizontal along one ground plane element.
