.: Welcom to PFS-TECO Satellite television is the technology which uses communication satelites located 37,000 km (22,300 miles) above the earth's surface for transmission. Satellite television has a transmitting antenna located at an uplink facility. Uplink satellite dishes are directed toward the satellite that its signals will be transmitted to, and are very large, as much as 9 to 12 meters (30 to 40 feet) in diameter. The signal is transmitted to devices located on-board the satellite called transponders, which retransmit the satellite signal back towards the Earth at a different frequency. The satellite signal is then collected by a parabolic receiving dish, which reflects the weak signal to the dish's focal point and is received, down-converted to a lower frequency band and amplified by a device called a low-noise block down converter, or LNB (Direct broadcast satellite dishes use an LNBF, which integrates the feedhorn with the LNB). There are two primary types of satellite television distribution: direct broadcast satellite (DBS) and television receive-only (TVRO).
