HS (High Strength) & TRX (Triaxial) Coaxial Cable

Designed for specific applications

Harbour Industries HS (High Strength) coaxial cables have been designed for applications where breakage or fatigue is a concern. Frequently, installation or termination and severe vibration of smaller size MIL-C-17 coaxial cables result in stressing of individual strands of the outer braid or the center conductor. To correct this situation, Harbour’s High Strength HIS cables have been designed with conductors exhibiting higher break strengths than standard silver plated copper. Accordingly, a flex life 25 times greater than comparable RG constructions can be expected.

Isolation of the shields and improved shielding

Periodically, isolation of shields in a coaxial cable is an important consideration. Harbour has designed a number of TRX (Triaxial) cables, expanding the product line offered in the MIL-C-17 specification. (Currently, the MIL-C-17 specification defines only one triaxial design — M17/131-RG403, a triaxial version of M17/93-RG178.) With an existing double braided design, an interlayer of insulation is used between the two braids. With a single braided cable, an interlayer and a second braid is used. Complete isolation between the braids is realized, in addition to achieving a more effective shield configuration.
