RG166 Coaxial Cable 50 Ohm 3 GHz Armored High Power Coax for Defense Systems

RG166 M17/65 is a MIL-DTL-17 qualified 50 Ohm armored coaxial cable engineered for applications where the transmission line must survive the same harsh conditions as the personnel operating it. Building on the foundation of RG165, this tactical-grade cable adds an outer layer of aluminum alloy wire braid armor over the fiberglass jacket, transforming a high-performance RF line into a field-ruggedized asset that withstands crushing, repeated dragging, and exposure to the elements. The core construction features a 2.39mm stranded silver-plated copper-clad steel (SCCS) conductor and taped PTFE dielectric, delivering stable electrical performance through 3 GHz. The single silver-plated copper braid and PTFE tape wrapping provide robust EMI protection and voltage isolation, while the fiberglass inner jacket and aluminum alloy outer armor create an impenetrable barrier against mechanical abuse. With 5000V RMS operating voltage, 6100W power handling at 100 MHz, and continuous operation from -55°C to +250°C, RG166 is the preferred choice for shipboard installations, mining operations, tactical communication shelters, and any environment where cables are expected to take a beating and keep working.

• Aluminum alloy armor – Outer layer of braided aluminum alloy provides battlefield-grade mechanical protection against crushing, impact, and repeated field deployment
• Tactical field survival – Withstands dragging across gravel, being stepped on, and exposure to vehicle traffic in forward operating environments
• 5000V operating voltage – Maintains high voltage integrity even when cable armor is subjected to physical stress
• 3 GHz frequency capability – Supports HF, VHF, UHF, and L-band communications across the tactical radio spectrum
• Stranded SCCS conductor – 2.39mm 7-strand silver-plated copper-clad steel provides the right balance of flexibility and tensile strength for field deployment
• Taped PTFE dielectric – Multi-layer PTFE tape construction ensures consistent 50 Ohm impedance and low signal loss
• Dual-layer protection system – Fiberglass inner jacket plus aluminum alloy outer armor creates redundancy in mechanical protection
• 250°C continuous temperature rating – Survives engine compartment heat, desert sun exposure, and industrial high-temperature environments
• 6100W power handling at 100 MHz – Suitable for high power transmitters in tactical and shipboard applications
• MIL-DTL-17 qualified – M17/65-RG166 for mission-critical defense applications requiring full traceability
• 11.94mm armored diameter – Robust construction that signals durability while remaining manageable for field deployment

• Shipboard and naval installations – Below-deck and weather deck cabling that must survive constant foot traffic, equipment movement, and salt spray without failure
• Tactical communication shelters – Field-deployed command posts where cables are repeatedly run over by vehicles, dragged across gravel, and exposed to the elements
• Mining and excavation operations – Underground and surface mining communications where falling rock and heavy equipment pose constant threats to cabling
• Forward operating bases – Temporary and semi-permanent installations where cables must survive rough handling during setup, teardown, and redeployment
• Petroleum drilling rigs – On-deck cabling on offshore and land rigs subjected to heavy machinery, foot traffic, and corrosive environments
• Defence vehicle installations – External cabling on armored vehicles exposed to road debris, weather, and combat conditions
• Test ranges and proving grounds – Temporary instrumentation setups where cables are repeatedly deployed, retrieved, and dragged across rough terrain
• Broadcast outside broadcast vans – Field production cabling that gets trampled by crew and equipment during live event setup
• Industrial manufacturing floors – Permanent installations in high-traffic areas where forklifts and foot traffic would destroy standard coax
• Construction sites – Temporary power and signal runs in active construction zones requiring maximum mechanical protection
