How to rig up a signal booster on a Bushnell Wireless Aggressor
 

I'm hunting an area where there is limited cell service and my Bushnell's don't work but our Covert cameras work with dual antennas. Has anybody been successful at adding a signal booster to the bushnell camera? After reviewing reviews on this camera not having the external antenna option is one of the biggest complaints with this camera. I love everything else about this camera.
