  1. Problems with the L/S band RF connector on the Columbus Module

  2. The Problem • The connector chosen for the DATV module RF input is unique to the ISS. • In Fact it is so unique that no additional connectors are available at this time. NASA and ESA stores have searched their stocks. • An acceptable substitute needs to be found

  3. HAM-TV system on ISS

  4. ARISS and AIS RF cable

  5. Suhner type N connector

  6. NZGC pins vs 21-033102/1 pins

  7. Connector pin Layout
