Thanks Alan, it worked using Imgur.com
See the trace that goes to the 6 pin RF Filter labelled FLT1 that is your RF Connection point.
You will have to solder to the Centre Pin of the RF connector to the centre PCB Board land and not the ones that are close by on either side.
I pulled the SMA connector so that you can get a better view of the PCB land that you will have to attach to.
Just remember that we are at 2.4Ghz here so take care both not for overheat the trace as well as NOT placing a large solder blob at the connection point as both will lead to RF impedance mis-match and could decrease your range. You probably will get away with it somewhat seeing as the PCB is a fiberglass FR4 0.062" which works ok at these frequencies.
( Please disregard the Capacitor above the label L41. fixed that after I took the photo )
Hope that this does help.
