It seems like many reverse bungee rides use some type of analog video transmission over RF for the front mounted face cam. If you watch some footage of a ride in progress the picture will often break up in such a way that looks like RF. Has anyone tried to receive a signal transmitted from the ball or know what band these cameras typically broadcast on? There is usually a box with whip antennas at the bottom of the ball which can give you a hint as to whether the ride has an onboard camera.
