I use an HD antenna for my tv.

Even when the antenna signal is showing good to excellent, I still get irritating "pixelation" in the picture.

Doing a channel rescan does not help.

Is anyone else experiencing this?

This never happened with analog TVs.

Digital is different than analog. It takes more signal for digital as a
general rule. Analog will fade in and out, sometimes even from an
airplane going over. If a digital signal is not received at 100% you
will get the pixelation. It is an either on or off condition where
analog will just fade. Sometimes on the old analog you would see what
is called a ghost. Where one picture will seem to overlay another but
be an inch or so to the right. This is when 2 signals arrive at
different times. If this hapens with digital, you may get the
pixelation.

There is nothing special about a HD antenna. Just advertising hype. It
is the same as the old UHF antenna.
