Description
54 to 2150 MHz DBS, OTA, CATV line powered amplifi er with 14 dB forward gain and passive sub band return.
SITUATION
DBS and CATV or Over The Air signals are required at multiple locations connected via coax cable.
SOLUTION
Model LA146R 6 Input Coax Amplifier With Return Path may be coax line powered from each RF output connector. Model LA146R-T includes an external power supply for direct powering. An energy conservation feature allows the amplifi er to operate effi ciently at 12 to 29 volts.
