The camera is most likely a 2.4 GHz. Like opjose said, a larger antenae won't help. Look on ebay for digital 2.4GHz recorders. They capture the image from your camera and record it to a Secure Digital card. Also the way it works with the VR helmet is by using the trainer port on your radio and selecting a couple of channels to be hooked up to a gyro on the helmet. This moves 2 servos under the camera and can pan/tilt with the movement of your head.
