Often one of the antennas is receive only. You would have to read the
manual to determie if this is true.

On the SMC 7004 family, they are "diversity" antennas.
I removed one, and put a reflector on the other, to improve coverage in my
home. One reflector and one stock antenna caused the diversity to toggle
poorly.

If there were two external antennas, routed to opposite sides of the
building, they would probably both function fine to those sides of the
building. Sector or panel directional antennas might improve that. The
problem arises when your client can communicate with a good antenna and a
poor antenna, and toggles between them, instead of staying with the good
one. Isolation between the two fields of coverage should eliminate the
hunting.

But the unit may function as "diversity receive", i.e. only one
antenna is used in transmitting. MIMO would have the ability to
receive and transmit on multiple antennas. [I know on my PCMCIA wifi
card, only one port can transmit. I've been thinking of setting up war
driving with an antenna on each side of the car since kismet doesn't
transmit.]

Maybe Jeff can chime in here. I'd certainly like to learn how to
provide free wifi without opening up my network to hacking. There is
the remote chance that someone would use the system for sending spam.
While spam is bad, having your IP blacklisted is worse.
