Cecil, I'll work w/ your s/s and play around some more w/ the helical
(just for the fun of it, ya know ;-) ).

You will radiate more power if you make the center half
of the antenna straight wire and use the ends of the
antenna for the helical part. If you haven't considered
top hats on the antenna ends, please do so. The following
would be a pretty good antenna, in fixed font with top
hat loading at the ends.

Isn't that a linearly loaded dipole?

I saw a picture of a similar antenna in some book I was browsing - the
illustration didn't show a center wire, just the coils and the top-hats.

Would you keep the wooden dowel form (for the coils), or would you let
them be air-coils (how to keep them from separating [tape])? What
lengths would you use for the wire/coils? What type feed line would you
use: twin lead or coax? Am I asking too many Qs?

Wait a minute... I've seen examples of this type of ant. on other
websites. I'll look those up and you won't have to answer these Qs,
which have probably been asked many times before.

N5ESE shows a linearly load dipole that is about 12 feet long (6 ft per
pole), twin lead fed with 14 inches of zig-zag wire at the ends. He
reports that he had pretty good results w/ this ant. on 15M and 20M (the
ant. was inside his bedroom at the time of the test).
