The catheter also includes an anti-bunching mechanism to prevent bunching of a protective sleeve disposed around the catheter tube, thereby reducing interference from the sleeve during insertion of the catheter tube. Optionally, the signal modules may include vias having conductive liners therethrough that electrically connect ground planes from opposite sides of a signal module to one another.
