A:AnswerYes you can use this modulator to connect a TV with only a coax connection. I used this modulator and RCA splitters to hook up two TV's with only coax connectors to my DirectTV DVR.
A:AnswerIt depends if your model of the ROKU has a composite video and stereo audio output. If it only has an HDMI output then it is not compatible with the Dynex RF Modulator.
A:AnswerYes, you should be able to. Usually you need to run the red white and yellow cables for the DVD portion and the coax cable for the VCR portion. That will let you run the DVD and the VCR with no issues.
A:AnswerIf the VCR has a composite video/audio output (red, white, and yellow connectors) this unit will do the Job. It will provide an output on NTSC channels 3 or 4.
A:AnswerNo, absolutely not! This device has a one way transfer function, That is it takes a NTSC format audio/video signal and produces a modulated RF signal at a particular NTSC TV channel. Usually channel 2 or 3.
A:AnswerYes, the DX-AD116 RF modulator will output stereo signal in the coaxial line. It was not designed for transmitting through a 200ft cable so I would recommend using a signal booster.
