Robust performance in a compact, heat-resistant footprint.
The RG316 is the definitive solution for high-frequency interconnections where space is at a premium and environmental conditions are demanding. Unlike standard PVC-jacketed miniature cables (such as RG-174), the RG316 features a Fluorinated Ethylene Propylene (FEP) jacket and high-grade PTFE dielectric. This construction allows it to withstand continuous operating temperatures up to 200°C, making it ideal for internal rack wiring, high-power transmitter pigtails, and soldering applications where other jackets would melt.
Why choose RG316?
This cable combines mechanical durability with electrical precision. The Silver-Plated Copper Clad Steel (SCCS) conductor and Silver-Plated Copper braid ensure exceptional conductivity and corrosion resistance, while the FEP jacket offers superior resistance to chemicals and weathering. It is the professional’s choice for ensuring signal integrity in harsh industrial or military-spec environments.
Key Features:
-
High-Temperature Resilience: Rated for -55°C to +200°C operation.
-
Superior Shielding: M17/113 spec 95% Silver-Plated Copper Braid provides robust protection against EMI/RFI.
-
Precision Impedance: Strictly maintained 50 Ohm characteristic impedance for low VSWR.
-
Durable Construction: The FEP jacket is chemically inert, tough, and UV resistant.
Applications:
-
Internal wiring for Test & Measurement equipment
-
GPS, Wi-Fi, and Telemetry Pigtails
-
High-frequency Interconnects (Jumper Assemblies)
-
Avionics and Military Communication Systems

RG316 is frequently used with SMA, SMB, MCX, and BNC connectors.
Pro Tip: Due to its steel core, RG316 is stronger than standard copper cables, but slightly stiffer. If you require maximum flexibility for a constantly moving part (like a hinge), consider stranded core RG-174, provided temperature is not a factor.
