Cable assemblies
Due to its 75 ohms characteristic impedance,
RG59 is rather dedicated to TV/Video
application.
Its solid inner conductor allows better
attenuation than the equivalent KX solution
(KX6).

Relevant standard: NF-C-93/550-KX6 (France)
Due to its stranded inner conductor, KX6 is
much more flexible than RG59.
This cable will be chosen instead of RG59 for
specific applications requiring high flexibility.
