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.

A P P L I C AT I O N N O T E S Model LAL20a and LAL204a amplifi ers have 20 dB automatic gain input windows to provide a clean fixed output. Model HRT116, HRT112, HRT109 and HRT106 directional couplers tap a portion of the signal to feed distribution nodes. The trunk level is indicated on the left and the tap level output is indicated on the right.
