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

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.

Too late! I've already built the 4-bay bowtie:

But I used ER70S-2 1/16 weld filler rod (stiffer than a coathanger, and
copper-plated; solders like a dream):

And it works just spiffy! I had to go to Whittier Electronics to get
the balun, since RS seems to have dropped them from their line-up:

It was $2.99; the rest of the antenna was free. :-)
(yes, I'm really that broke. )-; )

Thanks,

Thanks, Rich - - it looks great. I'm going to try putting one together,
too - - the phased quad bow-tie is very popular so it must be a good
performer. And the price is right.
