Satellite radio is a popular form of broadcasting. It transmits audio signals with greater clarity and frequency than terrestrial radio. Several satellites cover the continental United States, parts of Alaska, and Puerto Rico. The signal is usually free of advertising, and it offers clear, CD-quality sound.
Unlike AM and FM, satellite radio can be accessed from anywhere in the continental U.S., and can offer sports, news, and comedy programs. Despite its popularity, satellite radio is also expensive. Subscription fees vary from service to service, and there are a few things you need to know before choosing a plan.
Satellite radio is broadcast by a series of specialized satellites in geostationary orbit. Each satellite has three signal beams that overlap in a coverage area of about 14 million square kilometers. These beams can be retransmitted by a network of antennas to subscribers.
Satellite radio providers provide hundreds of channels for listeners. Some services, such as DirecTV, claim that they offer advertisement-free content. Nevertheless, most programs are subscription-based. If you are interested in subscribing to a satellite radio service, you’ll need a specialized receiver.
A lot of automakers have recently begun including one-button access to satellite radio in new vehicles. You can install a specialized receiver in your car, or buy a portable model.
Satellite radio has increased in popularity since it was introduced in 2001. In addition to its clear signal, satellite radios offer near CD-quality sound. This type of radio also allows you to listen to old-time radio shows, along with talk and music stations.
