Mil-C-17 Coaxial Cable
QPL Approved
Harbour supplies a complete line of high temperature, high performance QPL approved MIL-C-17 coax cables for the military,
commercial and industrial applications. The specific M17 constructions referenced are manufactured in accordance with the most
recent revision of the MIL-C-17 specification. The MIL-C-17 specification defines complete physical and electrical characteristics
for each M17 part number, including dimensional parameters, dielectric materials, shield construction, maximum attenuation,
and VSWR levels.
VSWR Sweep Testing
When selecting a 50 ohm coaxial cable, constructions with VSWR requirements are recommended. Manufacturing and sweep
testing cables with concern for VSWR ensures a quality cable free of spikes over the referenced frequency range. (Note the test
frequencies specified in the electrical characteristics section.)
Precision PTFE Dielectrics
All of the high temperature, high performance coax cables listed have PTFE dielectrics with high dielectric strength and low
capacitance in proportion to the dielectric constant. All PTFE dielectrics are manufactured with tolerances tighter than the
MIL-C-17 specification to ensure uniformity of electrical characteristics, especially impedance, attenuation and VSWR.
Tape wrapped PTFE Constructions
Harbour also manufactures PTFE tape wrapped cables to a previous revision of the MIL-C-17 specification. These constructions
can withstand operating temperatures up to 250° C. versus 200° C. for FEP jacketed cables. Also, PTFE tape wrapped cables are
generally more flexible than their FEP jacketed counterparts.
UL Approvals
All of Harbours M17 part numbers manufactured to the MIL-C-17 specification may be ordered with UL and FT4 approvals.
