Help with cable identification

[James True N5ARW]

I need some help identifying some coax.  It is government surplus
and does not have an RG number.  This is the information on the
spool.

manufacturer: Surpernant Wire & Cable, Division of LF Industries, Clinton, MA

number printed on the cable: 90484

government info:

6145004379860  (this might be a NSN)
cable radio frequency
500 feet
A  9/86
DLA500-86-M-EV82

I have a book that crosses national stock numbers to wire types
but it is too old to show this number.  Any help would be appreciated.

Thanks
