The MIL ratings are RMS Ian but there is no mention in the document of
the frequency. I and possibly others have always believed it to be 60Hz
AC.
I also can not understand the wide difference in DC vs RMS ratings that
you are claiming. I'll try and reach someone at Belden and get a
clarification.

Not in my shack!
