Default Log-Periodic Antenna Design

My current UHF antenna is a 14" Radio Shack clip lead clipped from the
center of my coax to the venetian blind. I have to hand-adjust it
for the channel, weather conditions, phase of the moon, etc. I can
do this because I can _see_ an indication of signal strength.

Well, with this new Fascist "No More Free TV" crap, I'm gonna need
a real UHF antenna. My budget is exceedingly limited, but I have
a supply of materials (GTAW filler rod, with some coppery-colored
coating, so it solders like a dream, and is as stiff as piano wire)
to build an antenna with.

It may not take too much antenna. I picked up one of the converter boxes
and hooked it to a 432 mhz beam at 70 feet and got 21 stations on the auto
tune. Then to a 9 element M2 2 meter bem and it picked up 29 stations.
This was at the end of about 130 feet of low loss rg-8 size coax and then 25
feet of rg-6.
Several of the stations were the same transmitter,but differant chanels on
the TV.
