In my tests it's easy to achieve >151 Mbps with a 40 MHz channel and
2x2.  So if you're using an 80 MHz channel (twice the speed) and only
one antenna (half the speed) you could still get 151 Mbps pretty
easily.

I wouldn't be surprised if your speed is being limited by something
else, maybe the host CPU or a slow interconnect on the station or AP
(USB perhaps?), so it doesn't look "worse" with only one antenna
because it should be at least twice as good when operating normally.

If you use wireshark or tcpdump you should be able to check the MCS
level of the packets and see that it's lower with fewer antennas.

Have fun,
