The above pictures show Bruce's Box Car Cam, complete with antenna.
  Bruce installed the camera in an AF Loco # 307
   Bruce extended the wires from the camera to circuit and mounted the circuit, my power supply, batteries, and my antenna into the tender.   He placed a plug between the tender and  engine.   He also removed the "E" unit from the tender and hard wired the wires to the tender pick-up so the engine only runs forward direction.

   He  ran the AF Loco with standard AF Motor on both AC and DC voltages.   Little or no interference from the motor on the video images.   It seemed to be less drop outs of video when ran on DC Voltages.
