Dan,
I published just such a design with 3 elements on a 6 foot boom (gain 5
dBd) and 4 elements on the same 6 foot boom (6 dBd). See Communications
Quarterly, Winter 1998, "Yagi/Uda Antenna Design, Part 1: A different
approach", pp. 49-59. It is fed directly with 50 Ohm line with a few
ferrite beads on the jacket. The 4-element job is extremely wide band and
has 25-30 dB F/B. I used it for over a year to work numerous Europeans and
Africans on 6-meters with my modest 100 Watts. I now have upgraded to a
similar type using 5 elements on a 12 foot boom with 8 dBd.
