The antenna I was referring to was described at Dayton in 2003, and has been written up in at least one journal article. Unfortunately, I had a hard disk crash in March and have not recovered most files, and a quick Google search failed to turn up the paper. I think I recall finding it on line -- I believe it is a product of some consulting Breakall did for an AM broadcast antenna firm, presented at Dayton for the amateur audience.

The antenna is 4 short verticals, ~45 feet, with horizontal loading wires extending at 90-degree angles to make up the resonant length. The bottoms of each vertical are series fed through short lengths of coax which are paralleled at the common feedpoint. The result is a relatively compact antenna with performance apparently comparable to a 1/4 wave vertical, but with a very convenient feedpoint impedance (~50 ohms).

I'll be glad to share a NEC-2 file with anyone who's interested.
