S40501
S40501 - 50 Ohm Coaxial RF Cable
S40501 is a 50 Ohm coaxial cable and the industry’s workhorse, with decades of proven performance in the aerospace and defense markets. The S40501 coax cable features dual shielding, the inner spiral shield providing a close-conforming shield similar to that of a semi-rigid tubing. When compared to RG405, S40501 has comparable attenuation figures and a considerably higher temperature rating. Impedance is precisely controlled for low VSWR’s.
