Seems like ON4UN in his LowBand DXing book used an omega match for shunt fed
where the natural reasonance was below the band: a series capacitor from the
feed line to the
feed point and a shunt capacitor across the feed point. I haven't tried it
yet. Values looked to be
in the 300pf range depending on how far out of the band to the point of
memory). There may be other schemes that work as well.
