Hi guys

Where around the world is 900mhz video downlink prefered. I bought some 900mhz range video equipment. I have a ground rx and 2 aircraft tx's. I didnt realize that 900 can not be used here in South Afica. I was hoping someone would be interested to swap for 1.2 but first want to find out where 900 is used and if its worth doing a swap with shipping costs.

Any advice will help

Regards
TtT
