RG405 is one of the most popular semi-rigid
RG cables.
RG405 will be prefered to flexible RG316
or RD316 for applications requiring high
frequency range, low attenuation, high
screening effectiveness, very small
bending radius and/or no spring back effect.
Due to the outer conductor coating (tin),
this cable will be used instead of RG405
for applications requiring high corrosion
resistance and improved solderability.
