3 Receiving Mobile Satellite TV
3.1 Signal Reception
The T7 System can be used to receive satellite television using a Direct Broadcast Satellite located 22,000
miles in space. This system requires a clear view of the satellite in the southern sky to maximize the signal
reception. Other factors, such as satellite coverage area, elevation angle and weather also contribute to the
signal quality (Figure 3-1).

3.3 Blockage Protection
Objects such as buildings, mountains, bridges, tunnels and trees may block the line of sight (LOS) view to
the satellite. Blockage protection allows you to continue watching television for up to 2 minutes, even
though the antenna is blocked and not receiving a signal from the satellite. It will take about 1 minute
of unobstructed signal to build 2 minutes of blockage protection. If a blockage occurs for longer than
2 minutes, the protection empties and has to start over. Once you clear the obstruction, it will take the
system approximately 10 seconds to reacquire the satellite signal and provide programming. If you change
the channel, the system will need another 1 minute to build the 2 minutes of protection.
3.2 Azimuth and Elevation
The DBS satellites are located in the southern sky. The T7 is a sophisticated mobile antenna with a satellite
recognition and tracking system. The antenna automatically determines and maintains the proper azimuth
and elevation angle without user intervention. This enables the system to receive satellite TV while
stationary or in motion.
