I didn't clarify myself, but the gap technology (I should have used
lower case) isn't necessarily the same as the GAP brand. I couldn't
find the book I have it in, but it is where a wire resonant on a
particular frequency brought close to another antenna will match the
system and radiate efficiently (I don't know how efficiently.) (this
is an oversimplification of what I am describing.)

That sounds like the method patented in 1996 by Gary Breed, K9AY (U.S.
patent #5,489,914). He allowed the patent to expire rather than renewing
it, so it's now in the public domain.

(You'll probably have to paste that back together. Or just go to
http://www.uspto.gov and look it up by patent number.)
