Cleroux of Ram Overhead Door Systems told the Canadian Broadcasting Corp. the problem began last weekend. Advertisement "It affects a 25-mile radius. That's huge," said Cleroux. Cleroux believes the culprit may be the U.S. Embassy. The new state-of-the-art Land Mobile Radio System uses the 390 megahertz frequency that is also used by almost all garage-door openers. Homeowners near military bases in the United States have had problems with the military signal simply overpowering their systems. If the U.S. Embassy is to blame, other diplomats are among the victims. Miguel Puna, Angola's ambassador, said he can no longer open and close the embassy's electronic gate.
