RG402 is one of the most popular semi-rigid
RG cables.
RG402 will be prefered to flexible RG142 for
applications requiring high frequency range,
low attenuation, high screening effectiveness,
very small bending radius and/or no spring
back effect.

(1) SPCCS = Silver Plated Copper Covered Steel
(2) PTFE = PolyTetraFluoroEthylene
(3) TPC = Tin Plated Copper
Due to the outer conductor coating (tin),
this cable will be used instead of RG402
for applications requiring high corrosion
resistance and improved solderability.
This cable is also an economical alternative
solution to .141 silvered copper.
