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.
