Here's an updated parts list to my original post. one part was wrong, female to Female SMA Coupler. I now have the correct coupler part link, a SMA Female to RP-SMA Female. These parts will allow you to do the camera antenna mod with out having to take the camera apart with the exception of taking just the cover off. Since I could not find a Male u.fl to Male RP-SMA cable, or a Male to Male U.FL cable. The following 3 parts will get the same basic job done.
The parts are as follows and will be listed with E-Bay links below. a 6 inch male to female u.fl cable. a male U.Fl to Male SMA connector. A Female to RP-SMA Female coupler.
How to do the mod.
Using a 1.5mm hex wrench you will remove the 4 screws on the bottom of the camera. Put a piece of tape over the button so it does not fall off when lifting the cover, first from the back then the front then lifting straight out. You will disconnect the cable plugged into one of the side facing square antennas into the male end of the 6" cable, then the female end into the adapter then screw in the twin female head sma coupler, then your antenna into that. Oh. And you will route the 6" antenna wire through existing vent holes on the plastic bottom so no drilling required. That's it, Easy.
Here's link to my video on the subject. Note, the video shows the wrong female / female sma coupler. I have an annotation noting the correction, The correct parts list is also in the video description as well as below.
