Autopilot servo too close to transponder antenna

Whenever I would turn my transponder on it would cause my autopilot servo too fail. My antenna was only about one foot from my roll servo. I moved my antenna about three feet away from the servo and no more problems.

FWIW - that situation is more prevalent in composite airframes & with VHF antennas too
