Due to its small diameter this cable will be
used for applications requiring flexibility.
Its low bending moment allows an easy
routing during installation.
The double braid provides a higher level of
shielding in comparison with 2mm single
braided cables.
In addition the solid inner conductor allows a
very good attenuation level.
The insulation and jacket materials allow this
cable to be used in severe thermal conditions.

Based on MIL-C17/93 US standard, this cable is
used where non magnetic aspect is required.
In addition the solid inner conductor allows
reduced attenuation in comparison with
standard RG178.
The insulation and jacket materials allow this
cable to be used in severe thermal conditions.
