2. Sup'R'Mod - Wikipedia

   en.wikipedia.org/wiki/Sup'R'Mod

   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]

   Class or connector name Used for Notes RF connectors (radio frequency signals). Generally use coaxial cable types such as RG-6 and RG-59 (except for twin-lead). Belling-Lee/IEC 169-2 connector TV aerial plug (a.k.a. antenna plug) Television antenna connection for most video devices outside North America. Used by early home computers and game ...

   The modulator is then programmed to broadcast the signals on a certain frequency. That RF broadcast is then received by the connected TV. When the TV is tuned to the programmed channel, the video and audio signal of the source device is accessed. RF modulation can become difficult in a CATV system. High pass, low pass, and notch filters must be ...

   This may then be converted to FM RF with an RF modulator that generates the proper carrier (often for channel 3 or 4 in North America, channel 36 in Europe). Sometimes this modulator is built into the product (such as video game consoles, VCRs, or the Atari , Commodore 64 , or TRS-80 CoCo home-computers), is an external unit powered by the ...

6. Digital television adapter - Wikipedia

   en.wikipedia.org/wiki/Digital_television_adapter

   A digital transport adapter will allow viewing of basic channels, often as many as 99, but not premium channels. It will also not allow video on demand or pay-per-view. DTAs also allow analog sets to receive digital signals using RF output on channel 3 or 4, using coaxial cable. Other versions of the DTA (including with an HDMI output) are ...

7. RF connector - Wikipedia

   en.wikipedia.org/wiki/RF_connector

   RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. Better models also minimize the change in transmission line impedance at the connection in order to reduce signal reflection and power loss. [1] As the frequency increases, transmission line effects become more ...
