3C-2V
3C-2V is commonly marked on low cost coaxial cable used for domestic TV signals.
It is one of the options of the Japanese cable standard JIS C 3501.
- The 3 indicates approx diameter of the conductive core plus the dielectric (diameter of conductive core =0.5 mm, dielectric thickness =1.3 mm)
- The C indicates a characteristic impedance of 75 ohms
- The 2 indicates a solid PE dielectric core
- The V indicates a single braided outer conductor (W would be double)
Nominal loss at 100 MHz is 42 dB/km.[1]
With its narrow core it is similar to RG-59 cable; RG-6 coax cable is better shielded and has lower losses.
