According to the manufacturer, normally there are two things to do. One, hang the antenna in the car over the driver's side visor as close to the door as possible. Also, if you have a 12V extension cord try the monitor on the left side of the steering wheel in the motorhome. Are you doing these things? Can you check the male threaded pieces on each unit to see if they seem loose? Hope these suggestions help.
