Hobby Wireless sent in this 3.3GHz FPV RC system for review and before I throw it on the bench, I'd thought I'd show you what sort of range and performance you can expect from this band at 10mW and 100mw effective power levels.
Due to the lower path loss resulting from the lower frequency (when compared to 5.8GHz), even a 10mW transmitter would actually provide useful performance for miniquads but 100-200mW would probably be the sweet spot.
The 1W unit supplied would give range well beyond visual line of sight even when used with omnidirectional antennas.
The legality of this system will vary from country to country and in most cases a ham operators license will be necessary so it is the responsibility of anyone considering the use of this system to ensure they comply with the relevant local regulations.
Disclosure:
The 3.3GHz video transmitter and receiver (plus VAS Bluebeam antennas) was supplied for review by Hobby Wireless:
