In summary:
- Receivers must not connect the signal shield/earth to their local ground. This could otherwise result in a ground-loop, adding noise to the received signal.
- Transmitters should ground the shield/earth.
- The ground/shield must be connected at both ends of a length of cable so that electrically this is connected along the entire cable segment, otherwise extension cables joined end-to-end would not be shielded.
