Used, in good condition. Tested within a working XL-DC receiver before removal. Possibly compatible with other TrueTime/Symmetricom/Microsemi GPS receiver units but this is not guaranteed. Note that the connectors are the Triax type and not BNCs. The fourth connector is sligtly out of round, but I believe that it will accept a Triax connector OK if you exercise care.
