Due to its 75 ohms characteristic impedance,
this cable is rather dedicated to TV/Video and
networks application.
Its small diameter and light weight make it
perfect to be used in all miniature, space
saving and dymamic applications.
For cost effectiveness reasons and for low
frequency applications, RG174 may be used
instead of RG316 when environmental
conditions like operating temperature allow it.
This cable is compatible with a large range of
connector series.
