we be located at the end of the cable run and the picture quality have always be poor particularly on the higher channel . a extra tv require that a 3 way splitter be add and the result be a picture that be degrade to unacceptable level . I buy the bda-s4 because the spec be good and also because it be make by Motorola . the amplifier perform beyond my expectation . the picture be clear on all channel include the higher channel which have never come in this good .
