My understanding is that device has only one antenna, or at least the atheros chip is wired for only one antenna, meaning only HT20 modes.
The PCB itself may have pads for two antennas depending on hardware revision (similar for product TL-WN703), but I've only seen parts populated for one antenna on the units I've opened up. Probably because the device's plastic enclosure is too small for correct spacing between two antennas.
