this dramatically improve the reception in my house . I have Insight Cable -lrb- Ohio -rrb- and have always have several snowy channel . the cable company have be out but say there be nothing they could do , as some channel just get poor reception . to make matter worse , I recently add five new splice for a total of 10 . several tv 's have terrible reception . I choose this model so I could run the main cable input into the booster and then each output to a splitter . the main cable line enter the house into a finished office so I also like how the unit be power , too . it work absolutely fantastic . all tv 's now have excellent reception . I just can not believe that this solve my issue . it seem very well make and sturdy and it be actually pretty neat how it work . the power source be a inverter that translate the house electric to 12v . you plug it into you outlet and then run a r59 or r6 coaxial cable from the power source to the amplifier\/booster . so I just fish a new cable line in the wall near my outlet to power it , as oppose to have to deal with install a new outlet near my cable input . I have broadband internet come through my cable and have see no interference or problem with that . it be always pretty good so I be unsure if there be any improvement . to I this be well worth the money . I have several lcd tv 's around and it suck to have spend the money on they but have bad reception .
