S31601 - Silver-Plated Copper-Clad Steel Coaxial Cable

S31601 is a 50 Ohm coaxial cable and the industry’s workhorse, with decades of proven performance in the aerospace and defense markets. S31601 is equivalent in size as the standard Mil-Spec RG316 coax but slightly lower in loss due to the extra inner foil shield. The additional inner foil shield within the S31601 achieves -90 dB shielding effectiveness compared to only -50 dB for a standard RG316 coax cable.
