HIS (High
Strength)
Coaxial Cable
Construction:
Center Conductor: stranded, silver plated copper clad steel (alloys optional)
Dielectric: solid PTFE
Braid: silver plated copper clad steel (alloys optional)
Jacket: FEP
Designed for specific applications
Harbour Industries 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.

TRX (Triaxial) Cable
Construction:

Dielectric: solid PTFE
Inner braid: silver plated copper
Interlayer: FEP

Jacket: FEP
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 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.
