S65161-A - 50 Ohm Coaxial RF Cable

S65161-A is a 50 Ohm coaxial cable and the industry’s workhorse, with decades of proven performance in the aerospace and defense markets. The S65161-A features a 100% shielded construction, incorporating both silver-plated copper spiral (inner) and braided (outer) shields. The electrical characteristics of S65161-A are comparable to standard RG393 coax cable, yet S65161-A weighs less than 25% of RG393 cable.
