What is a satellite radio?

Satellite radio is also called as digital radio. Since normal
radio frequency is very low, the signals can be limited and you
can listen to your favorite radio channels up to a certain limit
(40, 50, 100 miles). When you go beyond a certain mile your
radio won't get the proper signals. While going for a long
journey, you won't be able to listen to your favorite radio
stations. You need to keep tuning to get the nearest radio
station so that clarity is good. 

A satellite radio is a kind of static radio, wherein you can
listen to certain radio stations anywhere in the world. It's a
fixed and permanent radio station. No matter where you are, in
Florida or Texas, while traveling or at home, you can receive up
to 100 radio stations with very good frequency and of CD
quality. There are two-satellite radio services in the US -
Sirius and XM. Subscribers have to pay a monthly fee of $9.95.
Many car manufacturers have started installing satellite radio
receivers. If you want to listen to satellite radio at your home
or office you can buy a portable satellite radio and listen to
your favorite radio stations. There are many companies
manufacturing satellite radios and you can buy them online or at
retail stores. The radio stations of Sirius Satellite Radio and
XM Satellite Radio have their own program schedule. The programs
are available 24 hours a day, 7 days a week. Sports,
entertainment, talk shows and many other programs are aired.
