I have the chamberlain whisper drive wd822kd and my opener only works when i am standing very close to it, i live in a condo complex and i am assuming there is some one in the area that is interferring with my reception, i am wondering if the Liftmaster universal coaxial cable Antenna extension kit will work on this unit to give me better range??
