Yes, but in typical OTA networks, you have multiple transmitters and
multiple studios to choose from. Even if one fails, you can dial into
others. There are no single points of failure. Not even in your home, if
you own more than one TV set and perhaps a rabbit ear antenna.

Compare this with any cable or DBS setup. There are tons of single
points of failure. (I.e. points along a network which, if any one should
fail, will cut you off completely.)

In NYC on 9/11, even though most broadcasters depended on the one single
point of failure, the transmitter tower on the WTC, CBS did not, nor did
the stations in NJ. Hence, even in that somewhat unusual architecture,
OTA TV did not fail.

This sort of rural setting exists in Europe too. The only difference is
that over here, for whatever reason, people have relied on CATV systems
more than translators, to obtain coverage in such communities. So
coverage can be achieved, if there were a will to do so.

You can UNSUBSCRIBE from the OpenDTV list in two ways:

- Using the UNSUBSCRIBE command in your user configuration settings at 

- By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word 
unsubscribe in the subject line.
