So sorry you have a Spypoint. I have one and its terrible. Transmits ok but the detection circuits in them are
very poor. Can't pick up game animals and lots of false pictures. Plus I just got a notice from Spypoint that 3G networks
will shutting down so if your trail camera is using 3G I believe the cameras may no longer work. Here is an antenna that may work that
costs very little to try. I got this from Tacta-Cam and it says for Trail cameras but with 4G. If you try it and it works then let us know.
I hope this helps.
