My NDX2 is wired, connected to the same network as the iPhone, iPad and laptop that operate it. Does it still use or need the wifi aerials? If not, would it be better to remove them? My thinking is, a wifi aerial picks up more wifi signal than no aerial at all so if the NDX2 doesn’t use them, it might make sense to remove them?
IIRC, they’re both dual band antennas (mine are still in the box). It’s more likely that there are two wi-if antennas to allow for diversity switching or other measures to ensure consistent wireless performance and throughput.
