It's an Andrew standard for their non-braided coaxes.

##  as a side note, if RFS brand heliax is used, the turning radius is one heck of a lot less
than Andrew heliax.  The RFS stuff uses a corrugated cu center conductor as well as the
either cu or AL  corrugated shield.  Andrew heliax uses a copper tube on it’s  7/8”  heliax...
and also on its 1.25”  heliax.   The RFS stuff is flexible.   IF you get the version with the
AL corrugated shield, it’s also very very light.  That AL outer shield version only comes
in 2 sizes, 7/8”  and also 1.25” .  It’s a lot cheaper than andrew....esp if you get it at Davis RF. 
And of course, 7-16 Dins are readily available for both sizes.  The RFS stuff is a heck of a lot
easier to work with.
