Standards: M17/62-RG144.
Description: Flexible non magnetic coaxial cable of 75 ohm impedance for high power and high temperature with single silver plated copper wire braid, double teflon barrier tapes and double fiberglass jacket, external Ø 10.4 mm, for this reason it is often used as connection in high power amplifiers.
Application: RG144 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.
【Characteristic】
- 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.
- RG144 is similar in dimension to RG393, but impedance 75 ohm.
