Re: wireless? VHF of UHF?
True Diversity is a term coined years ago by John Nady to describe a wireless system that has two complete independent receivers housed in a single unit. The unit switches back and forth between the receivers depending on which is currently receiving a stronger signal. IMHO (once upon a time I worked an an engineer designing RF systems) True Diversity is a waste of money for the vast majority of musicians.
If you're really worried about RF interference look for a system that's frequency agile (i.e., one that at least automatically tests channels and selects the cleanest one(s) when it's switched on; or better yet, a true spread spectrum system). FWIW, I've used a cheap-ass Nady guitar system (not True Diversity, not frequency agile, not spread spectrum) for years with no problems at all. My company has used Shure's frequency-agile systems for recording seminars in a number of environments. We've done many, many hours with these and have never experienced intereference of any sort.
