Hi,

So the AR5416 and later NICs almost all implement MIMO. The only
exception is the AR9285 which is a 1x1 with the diversity
implementation matching previous (pre-11n) NICs.

Anyway, for MIMO, all the antennas are on by default. So yes, you need
to connect all of the antennas.

If you want to avoid this, you can override things. I _think_ it's:

hint.dev.ath.0.rx_antenna=0x5
hint.dev.ath.0.tx_antenna=0x5

in /boot/loader.conf

If it's not that, it's hint.ath.0.xxx ..

Then connect antennas to the connectors marked "chain 0" and "chain 2".

The boot messages should then say that the RX and TX chainmasks are being set.

Otherwise - yes, connect all three!
