Redheads and leather clothing notwithstanding, a stub is a whip is a
stinger is a 1/4 wave (or 5/8, or 1/2 wave, or...) Aunt Enna element.

Ok, thanks.  I'll be looking for it.  (I'm saving the series as a single
.TXT file).
 
I am FINALLY on 420, and I just might consider making a coax antenna for
it.  (It's just a little 1-5W HT).  At least I can get fully involved in
ARES now, and if/when a RACES chapter gets started, I'll be right in the
middle of that, also.
