   Composite video is received by the circuit board through a short cable terminating in a Molex connector, which plugs into a header on the Apple II motherboard. Input can also be provided through an RCA connector. The output of the RF modulator goes out through a coaxial cable to the antenna switch. [5] [6]

6. Composite video - Wikipedia

   en.wikipedia.org/wiki/Composite_video

   The process of modulating RF with the original video signal, and then demodulating the original signal again in the TV, introduces losses including added noise or interference. For these reasons, it is best to use composite connections instead of RF connections if possible for live signals and sample the source FM RF signal for recorded formats.
