The TERRA SA003 R82317 amplifier increases signal level of SAT IF signals in the 950 MHz - 2400 MHz frequency range. The amplifiers should be used in systems with long cables between LNBs and satellite receivers, both in the case of individual installations (single LNB and receiver) and in multiswitch systems. The use of the amplifier in such systems eliminates problems with low signal levels that could result in unstable reception of some channels.
