 This is an old newsgroup Text Info file!

 I just wanted to share what I can find from these lost archives Have fun!

THE FOLLOWING INFORMATION CAME TO ME FROM JOE LISMAN, K7PZH OF DOS PALOS, CA.
HE GOT IT FROM RAY MILLS, W6WIM, ALSO OF DOS PALOS.  THE INFORMATION SHEET WAS
TITLED:

The antenna boom is made out of schedule 40 pvc pipe, 1" size, which is 1.5"
in diameter, actual size.  The boom is approximately 42" long.  The cross
pieces are 1/4 inch bicycle flag poles made out of fiberglass, or you could
use fiberglass fence posts available from Orchard Supply Hardware stores in
California.

There it is folks and I hope that you are able to build it from these crude
instructions.  REMEMBER FOR VERTICAL POLARIZATION, YOU FEED A QUAD FROM THE
HORIZONTAL SPREADER END.  I think that one of the uses of packet should be the
desimination of information.  This is my attempt at a construction article.
How about some more homebrew projects with illustrations on packet radio.
I would be interested in reports from anyone who builds this antenna. Good
luck and I will look forward to your commeDoug, KI6DS @ K6RAU-1
