DBS Ka/Ku, ATSC off -air or SMATV signals are required

at multiple locations connected via coax cable. Signal

loss must be off -set.

Model LA144R may be placed after a DBS dish, ATSCantenna or SMATV headend to extend the signals the

equivalent of 150 feet of RG-6 cable.

LA144R amplifiers have a passive 2 to 40 MHz return

channel. They may be used to extend SWM8, SWM16

and SWM32 switch outputs.

Model LA144R-T ships with a power supply. Model

LA144R has no power supply and is intended to be

powered from the output coax cables.

LA144R-T

DIRECTV® recommends that the distance between

receiver and dish be less than 150 feet of solid

copper RG-6. At distances greater than 150 feet they

recommend a DC voltage booster and a line amplifi er.

Model 4SATPL-T provides LNB powering and strong

control signal to lock the dish. Without the locker,

receivers power the WB68 which must power the LNB.

Model LA144R amplifi ers may be powered by the

polarity locker for installations with long switch to

dish or receiver to switch installations. DISTRIBUTION

Model LA144R amplifi ers may used to extend the

output of SWM switches. The four outputs of a pair of

SWM16 switches or (1) SWM32 switch are extended

150 feet of RG-6.

For DIRECTV® (DRE) hotel systems, model SD SWMD2 diplexers are used to extract the DECA

signals originating from H25 receivers. Model

HRvS8P 8-way splitters send the SWM output and

DRE information to each motel room H25 receiver.

SONORA model S4x8DRE is an integrated hub

consisting of the LA144R-T amplifi er, (4) SD SWMD2 diplexers and (4) HRvS8P splitters.
