S33141 - 50 Ohm Coaxial RF Cable

S33141 is a 50 Ohm coaxial cable and the industry’s workhorse, with decades of proven performance in the aerospace and defense markets. The construction of the S33141 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, providing more uniform coverage and reducing attenuation due to aging and flexure. When compared to Mil-Spec coax cable, the S33141 cable is less than one third the weight of RG393 coax cable and approximately half the weight when compared to RG393, as well as more flexible and lower loss.
