I have a 8x1 cable splitter -lrb- cable to each room -rrb- and a splitter for broadband -lrb- before the 8x1 -rrb- . in addition , I get a tv tuning card for my pc that have separate input for analog and hd , so I need another splitter -lrb- after the 8x1 -rrb- . too many splitter be lower my video quality and make it difficult to receive hd signal on my tv tuning card . I leave the first splitter for the broadband -lrb- install by the cable co. -rrb- so that my broadband do not go through the BDA . then I insert the BDA on the video signal before the 8x1 splitter . now every cable output work perfectly with low noise on the analog channel and no difficulty on the hd channel . I have have this hook up for about 6 month now and never have a issue . it be nice to order something that work just as you would expect and hope .
