Jim...

Is there anything to be gained in putting a 1:1 "balanced isolator" at the feed point 
of an antenna that is fed by a "parallel wire" feed line? Does such an arrangement 
achieve feed line isolation while preserving the ability of such an antenna to be 
driven on various bands other than its resonant frequency? Thanks for your input.
