Sec. 22.361  Standby facilities.

    Licensees of stations in the Public Mobile Services may install 
standby transmitters for the purpose of continuing service in the event 
of failure or during required maintenance of regular transmitters 
without obtaining separate authorization, provided that operation of the 
standby transmitters would not increase the service areas or 
interference potential of the stations, and that such standby 
transmitters use the same antenna as the regular transmitters they 
temporarily replace.
