What I did was to capacity couple a dipole arrangement
which I placed very close to a antenna array to get a
constant impedance. The final set up comprises then of two occillators. This coupling method was picked up by a lot of people
because of its attribute of removing noise via
capacitive coupling. Basically the connecting impedance
point travelled along the length of the feed dipole
which also provided a broader bandwidth with a stable
impedance.

Hmm, never heard of it. If it's now effectively spread across the
antenna and amateur radio world, pray tell, how does it work? Be
specific, give examples.

Bet you can't.

Because never prove anything, ever. No examples with numerical values
available. Well, except that weird piece of crap yagi-ish thing you
once published here. The "pickup-sticks yagi" Not a particularly good
antenna performance wise. Ok, lousy.
