Well, with this antenna, there are two feedpoints... one for each polarization. He just hooked up the feedline to one feedpoint only I believe. It needs the matching section left on through... the loop of coax from one side of the feedpoint to the other.
( you know, it's too bad I already unboxed this KLM... I'd have offered to trade you. I have a Cushcraft 2m to go with it just like on the cover of the 416tb manual.)
