2. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   Assuming the dielectric properties of the material inside the cable do not vary appreciably over the operating range of the cable, the characteristic impedance is frequency independent above about five times the shield cutoff frequency. For typical coaxial cables, the shield cutoff frequency is 600 Hz (for RG-6A) to 2,000 Hz (for RG-58C). [10]

3. Wi-Fi over Coax - Wikipedia

   en.wikipedia.org/wiki/Wi-Fi_over_Coax

   As expressed by the minimum acceptable received signal strength indication (RSSI) for the client device, maximum range via Wi-Fi over coax varies based on transmit power of the access point radio chain, the wireless LAN (WLAN) frequency or frequencies being transmitted, the type and length of the cabling run, assembly loss caused by the ...

4. Characteristic impedance - Wikipedia

   en.wikipedia.org/wiki/Characteristic_impedance

   The characteristic impedance of coaxial cables (coax) is commonly chosen to be 50 Ω for RF and microwave applications. Coax for video applications is usually 75 Ω for its lower loss. See also: Nominal impedance § 50 Ω and 75 Ω

5. Twin-lead - Wikipedia

   en.wikipedia.org/wiki/Twin-lead

   Twin lead cable is a two-conductor flat cable used as a balanced transmission line to carry radio frequency (RF) signals. It is constructed of two, stranded copper wires, or solid copper-clad steel wires. The wires are held a fixed distance apart by a plastic ribbon that is a good insulator at radio frequencies (usually polyethylene).

6. BNC connector - Wikipedia

   en.wikipedia.org/wiki/BNC_connector

   The BNC connector (initialism of "Bayonet Neill–Concelman") is a miniature quick connect/disconnect radio frequency connector used for coaxial cable. It is designed to maintain the same characteristic impedance of the cable, with 50 ohm and 75 ohm types being made. It is usually applied for video and radio frequency connections up to about 2 ...

7. Radio over fiber - Wikipedia

   en.wikipedia.org/wiki/Radio_over_fiber

   By so doing, high frequency equipment can be centralized and high-loss, heavy and expensive coaxial cables can be replaced. [6] Typically this RF-over-Fiber technology is considered for transmission distances starting at about 50 meters.
