Default No More Free TV (was Log-Periodic Antenna Design)

So is analog. If you don't have the proper reciever, you can't pick it up.
Just a different format.


Even they used to be free, if you knew where to dumpster-dive. ;-)

Cheers!

That's not what conditional access means.

And the 80 year old method of modulation, a combination of pulse, FM,
and analog was just as much a restriction to specialized equipment. If
you tried to get TV on your XTAL radio, it would be like listening to
an encrypted secure network.

If you stood out in a field and tried to listen to AM radio waves
(without even the boon of that XTAL radio), you would still suffer
"conditional access."

So, what is the big deal?

Until you get to the requirement to line the pockets of the converter
hawkers.

The converter boxes are essentially free with the coupon and you get two
of them.

The current situation is somewhat analogous to what happened, decades
ago, when television in the U.S. moved from VHF-only to VHF-plus-UHF.

Everybody who wanted to receive the full set of channels, had to
either buy a new TV, or buy a UHF block converter so that they could
downshift the UHF frequencies to a VHF frequency that their existing
TV set could receive.

The television signal is, and will remain, free to receive (or,
rather, its transmission is funded by advertising). There is no fee
on the user to receive the TV signal.

The equipment needed to receive TV signals in the U.S. is not, and
never has been free.

This is a somewhat bigger switch-over, technology-wise, than the
expansion to UHF some years ago. Whether it's a Good Thing or a Bad
Thing is, I think, much more of a personal conclusion than anything
that can be decided objectively.

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.


Your clip lead is too long. Try 1/4 wave.

I got good reception using a 4 1/2 inch length of 24 gauge solid poked
into the F connector for a (line of sight) 45 kW station, 20 miles away.
(Most of the local stations run in the 500-1000 kW range).

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 I didn't fully describe how to get the file. It's a Word document, so
the URL above takes you to a page where you can choose "download", and then
you can open it with Microsoft Word.
