MIL-DTL-17 Coaxial Cables
- including M17/176-00002 Twinaxial Data Bus Cable
Harbour Industries is a QPL approved manufacturer of high temperature, high performance coaxial cables supplied
in exact accordance with the MIL-DTL-17 specification. The information referenced has been taken from the
MIL-DTL-17 “slant sheets” which define complete physical and electrical characteristics for each MIL-DTL-17
part number including dimensional parameters, dielectric materials, shield constructions, VSWR, and maximum
attenuation over various frequency ranges. For complete individual slant sheets, see the Defense Supply Center
Columbus (DSCC) link in the Industry Links section of Harbour’s website.
The Importance of VSWR Sweep Testing
When selecting a 50 ohm coaxial cable, constructions with VSWR requirements are highly recommended.
Manufacturing and sweep testing cables with concern for VSWR ensures a quality cable free of spikes over the
frequency range referenced on the slant sheet.
Precision PTFE Dielectrics Used
All of the PTFE dielectric coax cables listed are high temperature, high performance constructions exhibiting high
dielectric strength and low capacitance in proportion to the cable’s dielectric constant. Harbour manufactures all
PTFE dielectric cable constructions with tolerances tighter than the MIL-DTL-17 specification to ensure uniformity
of electrical characteristics, especially impedance, attenuation, and VSWR.
Constructions with PTFE Tape Wrapped Jackets
Harbour manufactures PTFE tape wrapped cables - specifically RG187 A/U, RG188 A/U, RG195 A/U, and RG196
A/U - in accordance with a previous revision of the MIL-DTL-17 specification. These constructions can withstand
operating temperatures up to 250 º versus 200º C for FEP jacketed cables. PTFE tape wrapped cables are generally
more flexible than their FEP jacketed counterpart. Alternative 250º constructions are also available with PFA jackets.
