RG119 MIL-DTL-17 Compliant Cable 50 Ohm High Power Low Loss RF Transmission Line
RG119 M17/69 is a MIL-DTL-17 compliant 50 Ohm high power coaxial cable engineered for applications demanding extreme voltage handling and thermal resilience. This heavy-duty transmission line features a 2.60mm bare copper inner conductor and taped PTFE dielectric, delivering reliable performance at 6000V operating voltage. The double bare copper wire braid provides robust shielding, while multiple PTFE barrier tapes and fiberglass outer braid jacket create a formidable barrier against moisture, abrasion, and extreme temperatures. With continuous operation from -55°C to +250°C and 334 g/m weight, RG119 is specified for high power broadcast transmitters, defense radar installations, and industrial RF heating systems where standard cables fail under sustained high voltage and thermal stress.

Q: What is the M17 designation for RG119?
A: M17/69-RG119 is the official MIL-DTL-17 part number.
Q: What is the voltage rating?
A: 6000V RMS operating voltage, significantly higher than standard RG cables.
Q: What is the maximum frequency?
A: 1 GHz (1000 MHz) as specified in the M17/69 documentation.
Q: What type of conductor does RG119 use?
A: 2.60mm solid bare copper for maximum conductivity and current handling.
Q: What is the temperature range?
A: Continuous operation from -55°C to +250°C.
Q: What makes RG119 different from other high power cables?
A: The combination of bare copper construction, PTFE barrier tapes, and fiberglass jacket makes it particularly suited for applications where cost-effectiveness and high voltage performance are balanced.
Q: Why use bare copper instead of silver-plated?
A: Bare copper offers excellent conductivity at lower cost. For applications not requiring the highest frequency performance, bare copper provides cost-effective high power transmission.
Q: What connectors work with RG119?
A: High power N-Type, SC, C, HN, and 7-16 DIN connectors designed for 11.8mm diameter cables with appropriate voltage ratings.
Q: Is the fiberglass jacket suitable for outdoor use?
A: Yes, fiberglass braid provides excellent UV resistance and weather protection for outdoor tower installations.
Q: Do you offer custom lengths?
A: Yes, RG119 is available in bulk lengths, cut pieces, or fully assembled with high voltage connectors.
