2. F connector - Wikipedia

   en.wikipedia.org/wiki/F_connector

   The F connector (also F-type connector) is a coaxial RF connector commonly used for "over the air" terrestrial television, cable television and universally for satellite television and cable modems, usually with RG-6/U cable or with RG-59/U cable. The F connector was invented by Eric E. Winston in the early 1950s while working for Jerrold ...

3. Diplexer - Wikipedia

   en.wikipedia.org/wiki/Diplexer

   A diplexer allows two different devices to share a common communications channel. Typically, the channel is a long coaxial cable, and a diplexer is often used at both ends of the coaxial cable. The plan is feasible if the two devices operate on different frequencies. The plan is economical if the diplexers cost less than running a second cable.

4. Analog passthrough - Wikipedia

   en.wikipedia.org/wiki/Analog_passthrough

   Analog passthrough is a feature found on some digital-to-analog television converter boxes. Boxes without the analog passthrough feature only allow older, analog-only TVs to view digital TV. Those with analog pass-through allow both digital and analog television to be viewed on older TVs. Before digital television, passthrough originally ...

6. Balun - Wikipedia

   en.wikipedia.org/wiki/Balun

   If a coil is made using coaxial cable near to the feed point of a balanced antenna, then the RF current that flows on the outer surface of the coaxial cable can be attenuated. One way of doing this would be to pass the cable through a ferrite toroid. The end result is exactly the same as a 1:1 current balun (or Guanella-type balun).

7. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   Coaxial cable, or coax (pronounced / ˈkoʊ.æks /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket. The term coaxial refers to the inner conductor and the ...
