AutoGain Amps LAL20a

DIRECTV® AU9S Ka/Ku signals need to be amplified to a constant high level and extended to multiple distribution locations.

SOLUTION

Optional External Power

SONORA model LAL20a & LAL204a may be placed as close as 50 feet from an AU9S dish and provide an automatic gain controlled output of -20 dBm (with 64 equal input transponders).

RELATED CONSIDERATIONS Multiple powering options. They may be coax line powered from either the RF input or RF output. Model LAL204a-T includes 12V, 1 Amp power supply. An external transformer from 12 to 20 volts may be connected. On model LAL20a, external power may be looped to power multiple amplifiers at one location.
