Flexible Coaxial Cables

PTFE Dielectrics for Commercial and Military Applications

MIL cables from elspec comply in all aspects with the requirement of the US STANDARD MIL-DTL. These products are continuously subjected to strict inspection during production. Test Reports in line with MIL-spec can be sent with shipment. Many RG cables, decised and stanardized for military projects in the past, are omitted from the latest MIL specifications. But this does not mean that they have all sunk into insignificance. For many years there will still be considerable demand for such cables as replacements and retrofits.
Elspec supplies an extensive range of there „rarities: RG213/RG218/RG220/RG302/RG303/RG402/RG405.

Why MIL-C-17 Coax Cables With PTFE Dielectrics Should Be Specified For Commercial and Military Applications

Harbour Industries was asked to evaluate samples of "RG178" and "RG316" coax cables that were supposedly manufactured in accordance with the MIL C-17 specification. At the very least, the cables were reported to perform with the same electrical characteristics as the MIL-C-17 specification. Here's the result.

Silver Plating Thickness
The RG178 under evaluation did not conform to the MIL-C-17 standards. The center conductor should have been annea led with a minimum of 40µ" of silver plating. However, it was hard tempered and had  only 29µ" of silver. This is typically done for cost cutting purposes . The hard wire can be processed somewh at faster but it is also brittle, less flexible and susceptible to  breakage under flexure. A reduced silver plating thickness makes the conductor susceptible to copper migration and galvanic corrosion. We were unable to prepare a sample of braid wire for a  silver  plating  test.  lt  proved impossible to disassemble the braid without breaking the strands. We couldn't determine if the braid wire was brittle or just difficult to disas semble. However, since the center conductor had an insufficient silver content, it is likely the braid  wire was manufactured under the same guidelines.
