DBS signals need to be amplifi ed to a constant level and

extended to multiple distribution locations.

DBS signals from -28 to -48 dBm input produce an

output level of -20 dBm as measured on the upper

transponders (2050 MHz).

Amplifi ers may be coax line powered from either their

RF input or RF output connectors. Model LAL205a-T

includes an external power supply.

Model LAL205a amplifi ers may be spaced at (5) fl oor

increments when used with model

HRT124, HRT120, HRT116, HRT112, H R T10 9 and H R T10 6 d i re c t ional

couplers.

Vertical versions of the taps HRvT106, HRvT109 HRvT112, HRvT116, HRvT120and HRvT124 are also available.

The trunk level is indicated on the left and the tap level

output is indicated on the right.

DBS / ATSC AMPLIFIERS

Model LAL205a provides automatic gain controlled

outputs of -20 dBm @ 2150 MHz with 32 equal input

transponders within an input window of -25 dBm

to -48 dBm.

LAL205a Power Options

Model LAL205a-T includes a 12 V, 1 Amp power

supply that may be use to power the amplifi er. DC

is connected to either the top right “12 to 20 VDC

AMPLIFIER POWER” input or lower right connector.

Power passes top to bottom or bottom to top if

additional items need DC power.

Model LAL205a & LAL20a-T amplifiers may be

used together to function as a LAL206a-T, (6) input

amplifi er. Power from the LAL20a-T loops to power

Model LAL205a amplifi ers may be used between

the SL5 LNB and model 5SATPL polarity locker.

The voltages generated

by the polarity locker pass

through the LAL205a to

power the amplifi er and

LNB’s and to polarity lock

the SL5 LNB.
