I haven't tested with equipment, but I am running several repeaters with two 2.4 Ghz cards in the same enclosure (on the same board) without issue. I am even managing to do it without any separation to speak of on the antennas, as they are mounted within 18 inches of each other in several cases. No apparent problems with interference that I can detect, as long as the channel separation is adequate.
