Been cleaning out the garage this weekend and came across an old attempt at
build a 432Mhz helix antenna. As I remember I gave up on it because I was
having trouble building the matching section which was a 11/4wl long fin
that attches to the helix as it apprached the feed point. It was proving
difficult for me to fabricate. I was wondering if the fin could not be
attached to the counterpoise instead of the helix, adjusting the space
beteen the fin and the helix to get a match.
