The orbital gamma match or gamma fed folded dipoles great idea to overcome the ability to switch polarity on a quad antenna. These were always good antennas for the size, the construction had alot to be desired for they would eventually fall apart. I searched for patent information on these antennas and had no luck, they information should be pre 1978. PDL II is a listed trademark of the former Avanti reasearch co.

Good Luck in your search.

Heres the Patent # for the original AV-120-2 (pdl-II) 3475756
The C.T.E. company owns the patent now, they bought it along with the Astro ground plane and star duster, They make it and call it the Bandit-II
