Spiral Antenna

I tried to make a spiral antenna today
http://www.google.com/patents/US6791508
I used this as an example but made the antenna for 50Mhz (6meter)
It worked great. It is a nice little antenna 8 inches high
and 12 inches in diameter. I did a radio check at 44 miles away at 100W.

I built it from 1/4 inch copper tubing.

Anyway that was my weekend.
