Third Antenna present?

[coflyer]

I haven't taken my T60 apart yet. I am trying to get all the pieces together before I do to replace my Intel 3495 card with an Atheros Card with "n". I was reviewing the specs that the T60 supposedly shipped with and noticed the following: 42R9190 VBB NO INT.WIFI WL 3RD ANTENNA
Does this mean that it has the 3rd antenna in it?

That is the FRU for a Wireless LAN 3rd antenna (14.1in)
