"WebDec 16, 2024 · Most of the rf signals picked up will stay on the outside of the shielding". This is only partly correct. The problem with a shield grounded on one end is that it can radiate any noise that makes its way onto the cable shield from the system - an antenna. This can cause you to fail a radiated emissions (RE) requirement. " - Grounded differential signals
