There are some non-mil-spec RG214 varients out there. Sometimes they are
labeled as "RG214 TYPE", or "RG214 Commercial". These typically have double
braid like "real" RG214, but unlike "real" RG214, the braids are bare copper
instead of
I believe that the real problem is that the center conductor is solid. A
slight nick in it will eventually cause it to break due to cable flexing
fatigue at the weak point. RG-400 is often used instead and has a stranded
center conductor.

42 has a silver-plated steel center conductor. repeated flexing can
cause the thin plating to fracture off creating duplex noise. i've personally
not had this problem but it is a documented issue.

What exactly do you mea
Yes, that was my point. Many of these cables do not experience flexing or
weather changes, yet exhibit the problems anyway.
