“Only power service drop or overhead service conductors shall be attached to the service mast,” according to the Residential Edition of the Florida Building Code (E3604.5) and the International Residential Code, and the National Electrical Code (230.28) 

    The service mast cannot be used for attaching cable TV (CATV), telephone, or anything else—including the security light shown above.
