of this converter and then use regular composite A/V cable to connect from the standard
video /audio output of this coax converter in RCA type to a TV display. No initial
configuration setup needed. No TV channel scan needed.
The operation of this coax video audio converter is 100% hardware operation. Easy cable
setup and no compatibility issues.
This coax cable signal agile demodulator can also be used a stand alone TV tuner. Featured
