MIL-C-17 Coaxial Cable

Harbour supplies a complete line of high temperature, high performance QPL
approved MIL-C-17 coax cables for 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 Dielectric Coax

　

All of the PTFE dielectric coax cables listed are high temperature, high
performance constructions exhibiting high dielectric strength and low

capacitance in proportion to their 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.

High Performance Polyethylene Dielectric Coax

Harbour also manufactures high performance solid polyethylene dielectric coaxial
cable, and is QPL approved to manufacture two versions of

RG217: M17/78-RG217 with VSWR requirements up to 3 GHz and the unswept version,
M17/165-00001. These cables have a high

maximum operating voltage up to 7,000 Volts RMS.
Tape Wrapped PTFE Constructions

Harbour 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. PTFE
tape wrapped cables are generally more flexible than their
FEP jacketed counterparts.
UL Approvals

All of Harbour’s M17 part numbers with PTFE dielectrics and FEP jackets may be
ordered with UL 1354 (80° C, 30 Volt) or

UL 1971 (150° C, 125 Volt) listing.
