Duck Decoy Remote Control Kit - 1x Remote, 2x Receivers, 6V Wireless Switch Set for Hunting Motion Spinner Decoys

One of my transmitters worked great. The other… not good at all. I rewired my connections multiple times- thinking it was my fault. Nope. Hope I can get some help!

works as intended

Too long to deliver. It was easy to install. BUT, the distance that it controls the decoy is less than 15 yards. Even placed a new battery in the remote. At most it sometimes works at 50ft away. Either the remote or reciever needs an antennae.
