Adding an external antenna to WiFi shield

-

i have looked info on how add external antenna arduino wifi shield, haven't found much. 1 post spoke briefly it, not enough info me feel comfortable it.

http://forum.arduino.cc/index.php?topic=127665.0

i used dfrobot wifi shield, , these had connector on them able attach 2.4ghz sma antenna.
i have few of these available no longer use dfrobot version.

could advise if possible, , how it?

the reason want because arduino board & shield mounted inside metal enclosure, , want put external antenna (with magnetic base) on outside, metal enclosure problem, if possible don't want have mount arduino + shield on outside of box.

there pads next icsp header connecting bnc connector antenna, labeled x4 on schematic.
not sure  - have remove chip antenna x1 avoid interfence?
