In this overly-long white-board based video, I discuss some of the theory behind long-range UHF radio control systems and the pro's and con's of using them. This video is the precursor to a series of reviews of a range of systems including:
- the Immersion EZUHF
- the DragonLink LRS system
- the Scherrer LRS
- the Arkbird UHF system
- the Open LRS (Orange) system
