this motorolum coax signal boster be well make and do improve my video signal . it do not come with a power cable -lrb- coax -rrb- , 75 ohm termination cap and wost of all no instruction ! I search on Google and be able to download the factory Motorola instruction . there be several inportant point make in the instruction book that should be take into consideration before attempt to hook it up . DO NOT boost the signal to your modem or router ! if you be not go to use all four output , order the 75 OHM termination cap at the same time .
