Diversity is certainly not a new concept. It was present
in the RCA AR88 designed about 1938-9!

I've seen pictures of AR-88s in triple diversity
set-ups. I don't know if that was ever used at the big RCA
Communications stations but at least one of the on-line
service manuals for the AR or CR 88 has a catalogue sheet
and photo of one in the back.
