§  73.811   LPFM power and antenna height requirements.

   (a) Maximum facilities. LPFM stations will be authorized to operate
   with maximum facilities of 100 watts ERP at 30 meters HAAT. An LPFM
   station with a HAAT that exceeds 30 meters will not be permitted to
   operate with an ERP greater than that which would result in a 60 dBu
   contour of 5.6 kilometers. In no event will an ERP less than one watt
   be authorized. No facility will be authorized in excess of one watt ERP
   at 450 meters HAAT.

   (b) Minimum facilities. LPFM stations may not operate with facilities
   less than 50 watts ERP at 30 meters HAAT or the equivalent necessary to
   produce a 60 dBu contour that extends at least 4.7 kilometers.
