APPLICATION NOTES FOR MIL-C-17

1. All cable has solid PTFE dielectric core.  Flexible cable has FEP jacket.  Semi-rigid cable outer conductor (shield) is bare copper.
2. The accommodating preferred connector for the RG180/U, RG302U and RG393/U is a 50 ohm SMA soldercup type.
3. There are no 75 ohm or 95 ohm impedance connectors to accommodate RG180/U or RG302/U cable.  Due to impedance mismatch, performance ratings are not applicable.
4. Only SMA Series connectors are recommended for flight use with MIL-C-17 cable at NASA Goddard.  (See application Note for MIL-C-39012 style connectors for details).
5. M17/93-RG178 and M17/95-RG180 have very small center conductors measuring 0.012 inches which are easily damaged during stripping, soldering or handling.  EXTREME caution is required during termination to connectors.  Use of cable with larger center conductors is preferred.
