When I get the desired match at resonance on the lowest band I intend
to use, the match is good from there up thru the higher bands where
the inductor becomes more transparent as freq increases.  One of this
type  coil is available comercially from  www.repdesign.us or you can
very easily wind your own by wrapping just 10-15 turns of something
like a 14 AWG wire around a broomstick for a form and attaching right
across the antenna feedpoint.
