This Stage Plus premade RF cable is a 0.5 m coaxial jumper terminated with Telegartner J01000A0014 BNC connectors on both ends and built on black RG58C/U coaxial cable. RG58 is a 50 ohm coax, the standard impedance used by wireless microphone and in-ear monitor systems, so this lead is used to connect receivers, antenna splitters, boosters, combiners and remote antennas within a rack or equipment case. A short 0.5 m length keeps rack cabling neat and signal loss negligible. It can equally serve as a general 50 ohm BNC patch lead for test equipment or video and word-clock connections that use BNC and 50 ohm cable. Telegartner is a German connector manufacturer known for precise RF connectors. Stage Plus is AV Distribution's South African house brand, and its premade cables are assembled locally from branded connectors and cable. For long antenna runs, a lower-loss cable such as RG8x or LMR400 is usually recommended instead of RG58. Price is for a single cable.
