I remember watching some white haired ol' weasel who, with a dual rhomboid
antenna, kicked butt in the 1296 MHz antenna gain competition at the 1996 CSVHF
Society gathering in Bloomington, Mn. You might take a gander at:
to see the competition in the 1296 MHz catagory.
I am happy that this subject came up and many thanks to W0OZI and W4RNL for
that piece of their lives that made me a believer.
