Hey guys, I recently set up three cellular trail cameras on my property in upstate New York ahead of the season. Two of them are sending pictures to my phone just fine, but the third one, located in a slight dip in the terrain, is barely transmitting anything. When I check the app, it shows low signal strength, but it still has a connection. Has anyone had success with adding external antennas, or is it better to just move the camera to higher ground?
