A number of omni-directional antennas can be acquired that will work with the BNC connector. A BNC antenna can be connected to a BNC antenna extension cable for a variety of radio applications working across AM, FM, HF, UHF and VHF frequencies. Radio: BNC Antennas with a BNC antenna extension have a wide variety of Radio Frequency applications making them useful in Ham radio connections.Video: BNC has an ideal impedance for video and the coax cable provides well shielded transmission.New ranges of custom and modified BNC HD connectors are now finding use for HDTV applications also. Television: The 50 and 75 ohm impedances of BNC connectors enable them to efficiently carry signal rather than power over distances making them a favorable choice in the television industry.Test equipment: BNC cables and connectors offer ease of use and a secure connection in test equipment such as audio generators, power meters and oscilloscopes.Aerospace: BNC connectors create a stable and robust connection that can endure the environmental pressures, temperature and pressure changes and vibrations experienced in aviation. ![]() The uses of BNC cables have since expanded to include a wide variety of Radio Frequency (RF) applications including: Originally developed for military use, BNC cables and connectors were initially adapted for use in early computer networks particularly those using Ethernet. BNC connectors usually work with frequencies of 4GHz or less with the 75 ohm connector specified for frequencies of around 2 GHz. These connectors have been made to match the impedance of the BNC cable to which they are attached and are typically available with 50 ohm or 75 ohm impedance typically. They possess a solder center pin and connect the braid of the coax cable to an inner ferrule with a stuffing-nut attachment. These connectors are again attached to trimmed and stripped cable.
