The 53534A has a 30.5cm cable (12-conductors, 6 twisted pairs, shielded)
terminated with a 12-pin round (circular) connector (Deutsch MMP 21C-2212P1).
This 12-pin circular connector is used with similar "all-in-one" receiver/antennas by
Motorola, Trimble, and Accutime.
The Mating Connector is: Deutsch MMP 26C-2212S1 composed of a 
molded back-shell (6810-204-2001) and 12 socket terminals (6862-201-22278).
Deutsch Connectors are now part of TE Connectivity (old Amphenol connectors),
check with your TE Connectivity electronics distributors. 

Synergy SYSTEMS (San Diego) may have those connectors available.

PHOTOS are available of what is "inside" this 58534A GPS Timing Antenna (circa 2008).
Includes schematic diagram for a DIY Interface box (5060-0184)
to convert the RS-422 to RS-232 and provide a 1 pps output.

A DIY interface box could be changed to USB (computer connection) 
with the proper substitution of a Silicon Labs or FTDI  -- UART (TTL) to USB bridge chip,
for the Maxim 232 device.

enjoy.
