Different kinds of satellite services use a wide variety of frequencies to transmit music, pictures, video and information. Three major types of satellites include TV, weather and radio systems.
Television
A range of different satellite TV bands exist. Most TV satellites operate at 250 to 40,000 MHz (40 gigahertz). The frequency will vary depending upon the model and service provider. The large, older dishes generally receive at around 4 gigahertz.
Radio
Subscription-based satellite radio services such as Sirius and XM also use high-frequency bands. The instruction manual for a Sirius One SIR-SV1B radio indicates that it uses 2,330.207 and 2,322.293 MHz to receive music and information from satellite transmitters.
Weather
Some of the weather information on television and the Internet comes from satellites, which prove useful for determining the position of clouds. Such satellites send their photos at between 136 and 138 megahertz on the VHF (very high frequency) band.
