RG119, High Power Coax, Up to 250℃, 11.8mm, 50 ohm

RG 119, Bing Cable

Standards: M17/52-RG119.

Description: Flexible non magnetic coaxial cable for high power and high temperature with double shield, double teflon barrier tapes and double fiberglass jacket, impedance 50Ω, external Ø 11.8 mm, for this reason it is often used as connection in high power amplifiers, eg. to connect the RF output of a tube cavity to the output connector on a rack panel.

Application: RG119 cable can work up to 250°C while other teflon cables are specified for only 200°C, for this reason it is often used in miltar equipment such as helicopters, tanks, etc... or where there are high temperature environments like wirings near a very high heat source.

  • PTFE precision insulation, high dimensional consistency, lower VSWR.
  • Used as connection in high power amplifiers.
  • Temperature Rating: -65℃ up to +250℃.
  • Double fiberglass jacket can resist instant fire.
  • PTFE insulation can withstand high welding temperatures without melting.
  • Compared with RG393RG119 has a larger outer diameter and higher power.
