HDTV Reception On The Road.

I am a traveler who loves to watch OTA TV stations on the road,
mainly deferent local news programs and stuff. I currently have
a nice portable SDTV that I know will soon be obsolete. My question
is if any of you have watched over the air HD on the road as of
yet? Is there any signal break-up, and is the signal still watchable?
I know that on the road SDTV used to be a pain with flickering,
however, I am wondering if HDTV corrects this problem or is
it much worse?

Depends on where you live. In many countries mobile digital TV is
possible today. Currently parts of Germany have mobile DTV possible if
you use a diversity receiver with two antennas. This works somewhat also
in the UK. China will build a national mobile DTV network.Works well in
Australia as this article demonstrates.

In the case of Australia it is also HDTV. In Europe there is no
terrestrial broadcast of HDTV although France will begin this year. The
French HD broadcast will be watchable mobile with a diversity receiver.
A non diversity receiver will work but not as well.

In the US our modulation will not allow for mobile reception on channels
2-51. This was a purely political decision and IMO should be reversed or
at least broadcasters should be allowed to use any of the far better
modulations being used by the rest of the world. But other broadcasters
will build mobile networks with spectrum that the FCC has and will
auction off. Since they have to buy this spectrum it will not offer free
OTA programming however.

Satellite DTV works but cost a lot and only works when there is direct
line of sight to the southern sky where the satellites are.

This actually works quite well. If you are already a subscriber, a
second dish and a small receiver you can easily carry back and forth is
all you need. I have also seen similar installations on RVs.

However, my impression was the guy wanted reception while moving! In
that case, I read somewhere that DirecTV is working on a deal with
somebody or other to do that, probably within the next year. I have
also read somewhere that a self-aiming antenna of some sort already
exists, but it is very expensive and too big for a car.

The only way to make satellite work behind a building, tree or hill is
if you install terrestrial based transmitters like XMRadio and Sirius
did. If you install terrestrial based transmitters it is really not a
satellite system anymore. It is really a terrestrial system that is
supported by satellites. The satellites are used mostly in rural areas
where it is less productive to place the needed terrestrial repeaters.
Sirius and XM are called a satellite system to get around the
terrestrial competition.

Technology is coming to terrestrial that will put satellite out of
business IMO. If special interest do not derail it as they do so many
new technologies.
