Land-Mobile-Radio (LMR) System Frequency Interference with Garage Door Openers
DASMA has received numerous questions from media and consumers regarding the issue of the U.S. military LMR (Land-Mobile-Radio) System and interference with the operation of garage door opener remote controls.
Following are some answers to common questions:
What problems might a homeowner experience?
When a nearby military radio system operates on the same frequency as the remote controls to your garage door opener, your remote controls may not work, even from a close distance. However, wired controls, such as a wall pushbutton, should continue to operate the garage door opener with no problems.
What is being done to solve the remote-control problem?
Garage door opener manufacturers are working with military and government officials to develop a solution that is best for homeowners and the military. Since many military and government personnel also enjoy the convenience of garage door openers, a mutually beneficial solution is best for everyone.
How widespread is this problem?
Throughout the U.S., as many as 40 million homeowners with garage door openers could be affected by interference from the military's new LMR system. The new system, mandated by the Department of Defense, began operating in 2004 at select military installations. However, that system is expected to spread to military bases nationwide.
