Description
Product Description

RG188 is a MIL-DTL-17 compliant 50 Ohm coaxial cable (M17/138-RG188) engineered for high-temperature applications requiring reliable RF performance in a compact form. Featuring a stranded 7/0.17mm silver plated copper-clad steel conductor and single silver-plated copper braid shield, this cable delivers consistent signal transmission up to 3 GHz. The PTFE insulation and PFA jacket enable continuous operation from -55°C to +230°C, making it ideal for aerospace, defense, and automotive industry where extreme temperatures and space constraints are critical factors.

Key Features
  • 230°C continuous rating – Handles heat that melts standard coax, perfect for engine bays and industrial ovens
  • Stranded SCCS conductor – Flexes without fatigue, outlasting solid conductors in vibrating equipment
  • MIL-DTL-17 qualified – Built to mil-spec for mission-critical reliability
  • PFA jacket – Non-stick, chemical-resistant, and tougher than standard FEP
  • Compact 2.5mm diameter – Routes easily through tight spaces and cable bundles
  • Low attenuation – Clean signal delivery from 100 MHz to 3 GHz

FAQ
Q: Why choose RG188 over standard RG316?

A: RG188 offers higher temperature rating (230°C vs 200°C) with PFA jacketed.

Q: What makes the 230°C rating possible?

A: The PFA jacket withstands continuous 230°C exposure while standard FEP jackets soften at 200°C.

Q: Is this cable flexible enough for tight routing?

A: Yes, the 7-strand SCCS conductor bends easily without work hardening.

Q: What connectors fit this cable?

A: Standard SMA, BNC, TNC, MCX, and MMCX connectors for 2.5mm diameter coax.

Q: Can it handle vibration?

A: Yes, the stranded conductor resists fatigue failure better than solid conductors.

Q: Do you sell by the foot?

A: Yes, any length with no minimum. Assemblies with connectors also available.
