Solder
the wires to the same board contacts where the stock antenna
was connected. The center of the coaxial cable is connected
closer to the miniature Hirose connector and the shield is
connected to the square contact [Fig. 10]. Be careful that
the solder does not jump the contacts.

It
is possible to test if the solder job is good with an Ohm
meter. There should be no connectivity between the outer ring
and the tip of your connector. If the Ohm meter reads "0"
either your pigtail is bad or your new solder job is bad [Fig.
11].

You
can test your external connector further if you wish. There
should be connectivity between the tip of your connector and
the tip of on-board Hirose U.FL-R-SMT miniature connector.
The outer ring of your external connector should also be connected
to the outer ring of Hirose connector [Fig. 12].

That's
all it takes. Now you can snap the enclosure back in place
and store the original antenna in a safe place in case you
ever want to put it back on.
