I bought this booster to work with my TPMS tire monitoring system for my caravan. First I tried the system without a booster, but the distance from each sensor to the monitor/display in my SUV was too far and I lost the signal from time to time. After installing this amp in the front of my trailer I had no problems with signal loss. Just completed my first long trip of 1550 miles in all conditions including rain, snow, ice and wind gusts in excess of 40mph and the system worked flawlessly providing air pressure and air temperature data for all 4 tires with no loss of signal between them. Tire sensors and monitor display. Highly recommended.
