How to get information about Antennas of an access point

Is there any diagnostic command, that could tell information about the antenna of an access point ?

i tried below command iw phy that shows-

phy1
        Available Antennas: TX 0xf RX 0xf
        Configured Antennas: TX 0xf RX 0xf

phy0
        Available Antennas: TX 0x3 RX 0x3
        Configured Antennas: TX 0x3 RX 0x3

So questions:
Which command or configuration file collects information about antennas os an AP?

what is the meaning of 0xf and 0x3 in result of above command?

Thanks in Advance ..

It is bitmask of available antennas
0xf = 1111b = 4 antennas
0x3 - 11b = 2 antennas

phy1 has 4 antennas of 5 GHz and phy0 has 2 antennas of 2 GHz.

is it right ?
