Hi Clay, Long time no see... When I lived in Minooka in the 60's & 70's our old friend from Kankakee who was with the TV cable company fixed me up with a lot of "scraps" of half inch and one inch 75 ohm foam dialectric solid aluminum encased coax. Some of it had a direct burial covering.

Well, my Wellbrook might work as well yours, as I too have worked CE/K7CA with mine on 160 from the Black Hole of KL7. More than once as well. For me the magic isn't directional gain, it's the improved S/N and the ability to null local single point QRN. If I were able to extend a Beverage or t
