The NS5 two small antennnas in it, one for each polarity. They have SNR but not RSSI, which I don't like. They don't currently do WPA2+WDS together very well; the firmware is improving quickly and has a lot of room for improvement, but is promising. You can't turn radio power down lower than 10dbm, and it's a 50/50 chance whether the radio will have an SMA or reverseSMA connector if you want to use an external antennas. I'd like to see a few more months of polishing before recommending them. We have only used them with MT and nanostation APs.
