Skip,

Jerry Sevick's book: "Transmission Line Transformers,"  (2nd ed.) =
describes a tapped trifilar transformer yielding an impedance =
transformation ratio of 2.25:1 exhibiting low loss (on the order of <0.1 =
dB) over the 1.2MHz - 30.0 MHz frequency range -- see page 7-17, figure =
7-14.

A little work, and you might be able to implement the same =
transformation ratio using a coaxial design for greater bandwidth.
