About RG402
RG-402 (UT-141) is a 0.141" semi-rigid coaxial cable with a solid copper outer conductor that holds its shape once formed. Its low loss and excellent phase stability make it the standard interconnect in microwave test setups, network analyzers, and laboratory bench assemblies. Ideal wherever cable position is fixed and mechanical rigidity is advantageous.
