MIL-C-17/62 | 75Ω | 3 GHz | 3700 V | -55°C to +200°C

The RG144U is a heavy-duty 75Ω high-temperature coaxial cable built for applications where standard cables simply cannot survive. While it maintains excellent electrical performance up to 3 GHz, its true strength lies in its outer defense: a silicone-coated fiberglass double braid jacket.

This advanced jacket transforms the cable into a ruggedized, waterproof, and highly abrasion-resistant transmission line. The double-braided fiberglass provides immense mechanical strength and tear resistance, while the silicone coating seals the braid against moisture ingress and prevents the glass fibers from fraying. Combined with an internal PTFE double-tape barrier and a stranded silver-plated copper clad steel conductor, the RG144U delivers uncompromised 75Ω signal integrity in the toughest mili tary, aerospace, and outdoor environments.
