Or, does anyone have a UHF-TV log-periodic design that they'd share? :-)

Thanks,

Lo and behold, here is one http://tinyurl.com/665r5a but it's a throw-back
to a simpler time when the HP42S calculator was an engineer's prized tool.
If you have a 42S, punch it in and use it. Otherwise, this is mainly a
learning tool to show how simple the calculations are. I think this design
could be put onto a Lotus123 calculating spread sheet where all the output
data windows would suddenly by filled up upon entering the needed input
data.

Sorry about the filename not working. This one should work:

Too late! ;-) I've already made the "coat hanger" four-bay bowtie, but
with weld rod rather than hangers. ;-)

It was on youtube:

Yep, it's all about the antenna. Hell, even a dipole tuned to the
midpopint of the band used for HD would get better performance.
