RG211 MIL-DTL-17 Compliant Cables M17/72 50 Ohm High Power RF Cable with Low VSWR

RG211 M17/72 is a MIL-DTL-17 compiant 50 Ohm high power coaxial cable engineered for the most demanding RF transmission applications where voltage, power, and thermal extremes converge. This heavy-duty transmission line features a substantial 4.88mm bare copper inner conductor and taped PTFE dielectric, delivering exceptional electrical performance through 3 GHz. The single bare copper wire braid provides robust shielding, while PTFE barrier tapes and fiberglass outer braid jacket create a formidable defense against moisture, abrasion, and extreme temperatures. With 7000V RMS operating voltage, 26,000W power handling at 100 MHz, and continuous operation from -55°C to +250°C, RG211 is the undisputed choice for high power broadcast transmitters, defence communication facilities, industrial RF heating systems, and any application where standard coaxial cables cannot survive the combination of high voltage and sustained thermal stress.

• 26,000W power handling at 100 MHz – Massive power capacity for high power broadcast, industrial heating, and research applications
• 7000V operating voltage – Engineered for the highest voltage RF applications, providing safety margin where 5000V-rated cables reach their limits
• 4.88mm bare copper conductor – Heavy gauge solid conductor minimizes insertion loss while silver coating enhances conductivity and corrosion resistance
• Taped PTFE dielectric – Multi-layer PTFE tape construction ensures consistent 50 Ohm impedance and superior voltage withstand
• Single bare copper wire braid – BC braid provides effective EMI shielding with excellent conductivity
• PTFE barrier tapes – Additional insulation layers between outer conductor and jacket prevent voltage breakdown at 7000V operation
• Fiberglass outer braid jacket – Exceptional abrasion resistance, thermal protection, and mechanical strength at 18.54mm diameter
• 250°C continuous temperature rating – Survives extreme heat in transmitter rooms, industrial ovens, and high power RF environments
• 3 GHz frequency capability – Supports HF through UHF applications across the broadcast and industrial spectrum
• MIL-DTL-17 compliant – M17/72-RG211 for mission-critical defense and government applications requiring full traceability
• 767 g/m heavy-duty construction – Substantial weight reflects the rugged, high-power design

• High power broadcast transmitters – AM, FM, and shortwave broadcast antenna feeders requiring up to 26,000W power handling at lower frequencies
• Defence communication facilities – Fixed-site defense transmitters where 7000V isolation and MIL-DTL-17 qualification are non-negotiable
• Industrial RF heating systems – Dielectric heating, plasma generation, and induction heating equipment operating at high power levels
• Particle accelerator RF delivery – Scientific research facilities requiring massive power transmission for beam generation
• High voltage test laboratories – RF component characterization at power levels exceeding 10kW with 7000V test requirements
• Petroleum exploration platforms – High power RF drilling and logging equipment requiring extreme durability
• Medical diathermy and RF ablation – High power therapeutic equipment with stringent voltage requirements
• Antenna test ranges – High power measurement setups requiring low-loss transmission lines
• Research and development facilities – Custom high power RF experiments where standard coax would arc or melt
