Thousands of satellites orbit the earth in geosynchronous orbit. This means that they are circling the earth in a band around the equator at an altitude of about 22,300 miles. Most of these satellites are there to provide television service. They are waiting to send signals to dish antennas on earth. In recent years the number of dish antennas picking up these satellite TV signals has been increasing rapidly. Prior to 1996, most of these dish antennas were huge, ugly monstrosities that took up big chunks out of a yard. They were visually unappealing. They were also susceptible to wind damage and other problems due to their 10-foot or larger diameters. For many people cable reception presented a better option than these antennas. Hughes Aircraft Company launched the first high-powered direct broadcast satellite (DBS) in December 1993. This satellite provided 150 television channels, which could be received on much smaller dish antennas. These new antennas were only 18 – 24 inches in diameter. With this improvement in technology, a rapid advance in satellite TV entertainment was about to explode. The much smaller dish antennas that come with free satellite dish TV systems are more attractive to household TV viewers. They can be inconspicuously mounted on roofs or the sides of houses. Their small size renders them much less susceptible to wind damage or accidental damage from lawn care equipment. And, the DBS technology is much more powerful, providing clearer, stronger satellite television signals to viewers. The new dish antennas is clearly a case where smaller is better.
