The SRD-AMP-1 is an inline amplifier intended for use in overcoming cable and splitter losses in a Crestron® XM or SIRIUS® satellite radio distribution network. It is rated to provide 16 dB (typical) of gain in the satellite radio band (2320-2345 MHz), and is powered from the DC bias voltage (4.5 VDC to 6.5 VDC) provided by the antenna connection on the satellite radio tuner downstream. It is also designed to pass DC voltage to provide power to the antenna and other line amplifiers installed upstream.

Placed at the beginning of a cable run, a single SRD-AMP-1 line amplifier will overcome the loss of approximately 150 ft of standard RG-6 cable. Up to two amplifiers may be cascaded at one spot for a total of 32 dB of gain to overcome the loss of 300 ft of cable. Cable runs in excess of 350 ft are possible using quad shielded RG-6, with additional SRD-AMP-1 line amplifiers installed inline as necessary, spaced equally along the cable run to prevent overload and distribute the gain properly.

An F-male coupler is included for use in connecting two line amplifiers in cascade.
