2. 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 ...

3. RG-6 - Wikipedia

   en.wikipedia.org/wiki/RG-6

   RG-6 coaxial cable for television signals. RG-6 coaxial cable. RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. An RG-6/U coaxial cable has a characteristic impedance of 75 ohms. The term, RG-6, is generic and is applied to a wide variety of cable designs, which differ from one another ...

4. SMA connector - Wikipedia

   en.wikipedia.org/wiki/SMA_connector

   SMA ( SubMiniature version A) connectors are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw-type coupling mechanism. The connector has a 50 Ω impedance. [ 1] SMA was originally designed for use from DC (0 Hz) to 12 GHz, however this has been extended over time and ...

5. RG-59 - Wikipedia

   en.wikipedia.org/wiki/RG-59

   RG-59/U is a specific type of coaxial cable, often used for low-power video and RF signal connections. The cable has a characteristic impedance of 75 ohms, and a capacitance of around 20pF/ft (60pF/m). [ 1] The 75 ohm impedance matches a dipole antenna in free space. RG (for radio guide) was originally a unit indicator for bulk radio frequency ...

6. 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 ...

7. RG-58 - Wikipedia

   en.wikipedia.org/wiki/RG-58

   RG-58. RG-58/U is a type of coaxial cable often used for low-power signal and RF connections. The cable has a characteristic impedance of either 50 or 52 Ω. "RG" was originally a unit indicator for bulk RF cable in the U.S. military's Joint Electronics Type Designation System. There are several versions covering the differences in core ...
