Video Sender Only Transmits One Channel
Can I connect my Video Sender directly to a coaxial cable or antenna feed?
No. You need to use a VCR or a cable box. The Video Sender only has RCA audio/video inputs, and it only transmits one channel at once. If you run the cable TV signal directly into a VCR or cable box, that box will output one channel at a time into the Video Sender. You can then use the IR extender feature of the VK82A sender kit to change the channel on the VCR or cable box.
