Radio Antenna (88 5K)

["Christopher Ritchie" <cjr1@gte.net>]

My power antenna only extends 16 1/4 inches in total length from the top of
its plastic tip to the top of the fender.  Some of that length is the
fitting on the fender.  Is that right?  There are 4 sections.  It will not
extend further when manually pulled.  I thought I remembered something
about FM radio wavelengths being 34 inches and therefore the antenna should
be some multiple of that length (17" or 34") for optimum reception.
