STANDARD AND CUSTOM CABLE ASSEMBLIES   FLEXIBLE * SEMI-RIGID * TWINAXIAL * HELIAX * FOAMFLEX     PRODYN's expertise in producing pre- cise, quality EM instrumentation makes them uniquely qualified to also produce cable assemblies that are used for EM measurements or many other applications. PRODYN regular- ly produces standard cable assemblies but also specializes in RF type pre- cision cables with any length, con- nector style or bend configuration. All cables are built in our factory using the highest quality U.S. and/ or Swiss components.   Industry standard connectors such as N, SMA, BNC, TNC, SMB, HN or many others can be built to your specifi- cations on practically any available RG type cable. Semi-rigid cables are routinely built using .034, .047, .070, .086, .118, .141, and .250 coax. Special soldering techniques allow PRODYN's technicians to build semi-rigid cables using pure alum- inum outer and inner conductors. Special application cables using connectors such as 100 ohm twinaxial modified GR style or GHV can also be made to order.   PRODYN has excellent sources for custom connectors that are not com- mercially available, which typically are modified versions of existing types. Every effort is made to keep delivery time to a minimum on these types.   PRODYN uses state-of-the-art test equipment to verify performance for insertion lees, VSWR, high voltage, resistance and time domain. Cables used for delay lines can also be built to your specifications, by themselves, or in custom packaging.
