RG120 Coax M17/52 50 Ohm Armored High Power RF Cable for Defence and Industrial Use

RG120 M17/52 is a MIL-DTL-17 compliant 50 Ohm armored coaxial cable engineered for the most demanding field applications where mechanical protection is as critical as electrical performance. Building on the foundation of RG119, this heavy-duty transmission line adds an extra layer of aluminum alloy wire braid armor over the fiberglass jacket, providing unparalleled protection against crushing, abrasion, and physical abuse. The core construction 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 PTFE barrier tapes and fiberglass outer jacket offer thermal and environmental protection. With continuous operation from -55°C to +250°C and 425 g/m weight, RG120 is the preferred choice for defence tactical deployments, shipboard installations, and industrial environments where cables are subjected to constant mechanical stress and must survive in the harshest conditions.

• Aluminum alloy wire armor – Extra layer of braided aluminum armor over fiberglass jacket provides superior protection against crushing, rodent damage, and field abuse
• 6000V operating voltage – Engineered for high voltage RF applications where standard coax insulation would break down
• Bare copper double braid shielding – Two layers of bare copper wire braid provide 95%+ shielding coverage with excellent conductivity
• 2.60mm bare copper inner conductor – Heavy gauge solid conductor minimizes insertion loss for high power transmission
• Taped PTFE dielectric – Multi-layer PTFE tape construction ensures consistent impedance and superior voltage withstand
• PTFE barrier tapes – Additional insulation layers between outer conductor and jacket prevent voltage breakdown
• Fiberglass outer jacket – Exceptional thermal protection and mechanical strength before armor layer
• 250°C continuous temperature rating – Survives extreme heat in engine compartments and industrial ovens
• 425 g/m rugged construction – Heavier than RG119 (334 g/m) due to additional armor layer
• MIL-DTL-17 qualified – M17/52-RG120 for mission-critical defense and aerospace applications
• 13.3mm overall diameter – Robust armored construction for industrial and defence field installations

• Defence tactical deployments – Field radio shelters and mobile command posts where cables are dragged, stepped on, and exposed to rough handling
• Shipboard installations – Below-deck cabling in naval vessels requiring extra protection against vibration and mechanical stress
• Industrial manufacturing floors – Heavy equipment areas where cables risk being crushed by machinery or foot traffic
• Broadcast transmitter sites – Outdoor runs between transmitter buildings and antenna towers requiring rodent protection
• Mining operations – Temporary and permanent installations in underground and surface mining environments
• Petroleum drilling rigs – High vibration areas where standard coax would fail under constant mechanical stress
• Test ranges and proving grounds – Temporary instrumentation setups where cables are repeatedly deployed and retrieved
• Aircraft ground support equipment – Heavy-duty connections between ground power units and aircraft
• Defence vehicle installations – Armored vehicle internal and external wiring requiring battlefield durability
• Construction sites – Temporary power and signal runs in active construction zones
