poor remote range

[Mark]

You would need to connect the inner of the coax onto the single piece or wire and the outer of the coax could be attatched to the case of the garage motor. This can be tested by just adding a piece of wire to the single wire ariel and poking it outside the door. However many things can cause this problem if you radio reciever inside the motor is developing a fault or if you have local interference blocking you signals adding the ariel may or may not help
