Sounds to me like you need a yagi antenna for the camera
mounted on the roof of the booth with a rotator. Get a
cheapo tv antenna rotator at your friendly rat shack, put
the yagi on a mast atop it, the operator can then turn the
antenna to track the camera, meaning either the sound
operator or somebody else. rEmote the antenna making it
have a better coverage area and use a regular antenna
rotator.
You don't need a heavy duty rotator for a yagi for those
frequencies.
Hope that helps.
