for at home and on the go
The "normal" satellite dish that we know from home can be used to receive television programs as well as numerous radio programs. For a fixed location, that's a great thing. But if you want to be supplied with satellite radio in your car, this is also possible in some parts of the world - for a fee.
In the car, the signal coming from the satellite is received either through the windshield by a special device that is connected to the car radio, or via a small external antenna. Some vehicles can be ordered from the factory with a satellite radio.
There are also small, portable satellite radios and home radios that can be placed by the window. A clear view of the satellite is of course a prerequisite.
