I should publish soon my findings about multiple radio.

Basically the more seperation in frequencies the better.

If you want to use 2 different channels in the 2.4 band, try to use
ch1 and ch13 or example, or at least non-overlapping channels (ex:
1-6-11).

If you are using omnis, try also to have Hpol and Vpol for better seperation.

In the 5gh band, use 5.2 and 5.8 in order to maximise the seperation.
