Signal loss must be off-set. Model LA144R may be placed after a DBS dish, ATSC antenna 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 (4) INPUT AMPLIFIERS LA144R Indoor / Outdoor 54 to 2400 MHz DBS / SMATV line powered amplifiers with 14 dB gain and 2 to 40 MHz passive sub-band return. 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 amplifier. 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 amplifiers may be powered by the polarity locker for installations with long switch to dish or receiver to switch installations.
