This amp solved my problem of losing or dropping communication with transmitters on my 32ft RV. I liked that no configuration is required - just plug it in, the green light on and everything worked. After several rides not a single drop. Mounted on the front of the trailer body beneath the hitch frame and hardwired to a 7 pin harness (pin 1 negative, pin 4 positive) for automatic power supply when the trailer is coupled to the tractor.
