Tis a modified feed system that is often used with a double bazooka. Think
there was an article on this feed system in one of the Antenna Compendiums.
The dipole itself doesn't exhibit any more bandwidth however the feed
system fools the transmittter. While it allows the individual to use the
same antenna over a wide bandwidth, it is not very efficient from a
radiator standpoint. IMHO if you want an efficient broadband radiator, use
a doublet fed with ladderline and a tuner.

Subject: [TowerTalk] dipole bandwidth
A local OF (no names please) reports good success in broadbanding his
80-meter dipole. Sez he feeds it with 50-ohm line, cut by formula for
3650, and inserts a quarter-wave of 75-ohm coax a quarter wave down from
the feedpoint. He says it produces a double-humped SWR curve that never
approaches 1:1 but stays between 2:2 from 3500-3800.
Anyone ever tried this?
