I'm pretty sure we are using the original D-Link connector, but will double check. Thanks for the suggestion.
I did look at some pictures of innards of the D-Link to see where the antennas are located. It looks like they use a dual antenna configuration for diversity... with the antennas in the corners of the enclosure.

Ant 0 is in the upper left corner of the picture and Ant 1 is in the upper right. Both antennas are on the same side of the D-Link as the LEDs (I guess you'd call it the "front").
