I just wanted to mention to those that consider using 1.2GHz video senders, they are not legal in NZ. But more importantly, the 1.2GHz band is also used for distance measuring equipment in New Zealand for aviation/aircraft.
Even if it's using something in the backyard, aviation navigation is not something to cause interference to.
Cheers,
