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

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

HAM-TV system on ISS

ARISS and AIS RF cable

What to do?

• A solution needs to be found.– 1. KI supply the needed special connector(s) to the

ARISS team– 2. Build an adapter cable that allows an N Female

connector to be used on the Beacon module.– 3. Any other ideas?
