LOL ... talk about trolls! That HAS TO BE THE BEST TROLL OPENING LINE I
HAVE EVER SEEN!

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.


Well, that is the second best ...

But I've been searching the web for some weeks now, and I can't
seem to find any kind of formula, except there was this program
I downloaded - LPDA.EXE, which runs on DOS. Unfortunately, it's
in Russian or Polish or Uzbekistani - one of those East Yurp
languages. Here's a screen snap:

hmmm ....

Which I went through pretty much by-guess-and-by-gosh - can
anybody read that stuff?

There are a lot of factors I don't know about, like "Tau", and
all of the specific designs on the web are flat - something is
telling me I want one of those pyramid-shaped ones, but I really
don't know the difference (between that and flat) - it's probably
something to do with bandwidth or F/B ratio or whatever.

My local library has no ARRL Antenna Book (!), and did I mention
I have a seriously limited budget?

So, how do I pursue this? It'd be nice to have a program that will
calculate the whole thing for me, but am I dreaming? If I want to
send myself to Log-Periodic School, where should I start?

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

Thanks,
Rich

It's not a troll. I bought a fair good UHF-VHF antenna,
assembled it and sat it on a saw horse in the driveway
for test, and it tested perfect for 3 channels + ch.34 .
So I set her up using a roof mount and LOST ch.34,
and no amount of rotating got it back.
(I was a pro antenna/tower installer as a kid).

Next I'm going to tape wire on 1/8" panelling and do
experiments ... ugh, I hate trial and error.

OK brother, you may not be what I accuse you of ...

But darn, the antenna you bought was designed with certain parameters in
mind ... I would seriously doubt you are going to vastly increase
performance with the route(s) you have described here ...

Sorry if I made a joke. But, my advise to you would be, if you saved
your receipt, take it back! DON'T HACK THE ANTENNA!

Chat with buddies or someone who has had better experience(s) (or,
varied experiences) with a better antenna, one which would serve you better.

Without expensive instrumentation and experience of years of
experimenting, it is hard to accomplish what I perceive your goals to be ...

I would never say anything is impossible, just what I feel is the best
advise I can provide you with in hoping for your best success.

Wish you the best,
JS

I bought one, a Phillips MANT310/MNT310F - didn't work
as well as the non-amplified RS one I already had.

Actually, I had to construct my own with a broadband MMIC device, to get
decent functionality ... however, my mother has an el-cheapo unit she
purchased from some yard sale, it/they work surprisingly well!

Location, reflections, etc. can vary ones experience greatly--but hey,
they usually beat a wire coat hanger! :-)

Hey, "John Smith", why don't you go outside and play
