S44193 - 50 Ohm Coaxial RF Cable

S44193 is a 50 Ohm coaxial cable and the industry’s workhorse, with decades of proven performance in the aerospace and defense markets. S44193 is equivalent in size as the standard Mil-Spec RG400 coax cable but offers lower loss and improved shielding due to its construction. The construction of the S44193 features a multi-layered shielding that combines conventional shields with an inner braid woven of flat strip of silver plated copper which reduces attenuation at frequencies over 1GHz when compared to round wire braids in standard coaxial cable.The cable VSWR is lower because the braids can be applied more uniformly. The attenuation and VSWR variation due to aging and flexure is substantially less.
