§ 90.635   Limitations on power and antenna height.

   (a) The effective radiated power and antenna height for base stations may
   not exceed 1 kilowatt (30 dBw) and 304 m. (1,000 ft.) above average terrain
   (AAT), respectively, or the equivalent thereof as determined from the Table.
   These are maximum values, and applicants will be required to justify power
   levels and antenna heights requested.

   (b) The maximum output power of the transmitter for mobile stations is 100
   watts (20 dBw).

   ^1Power is given in terms of effective radiated power (ERP).

   ^2Applicants in the Los Angeles, CA, area who demonstrate a need to serve
   both the downtown and fringe areas will be permitted to utilize an ERP of 1
   kw at the following mountaintop sites: Santiago Park, Sierra Peak, Mount
   Lukens, and Mount Wilson.

   ^3Stations with antennas below 305 m (1,000 ft) (AAT) will be restricted to
   a maximum power of 1 kw (ERP).

   ^4Licensees in San Diego, CA, will be permitted to utilize an ERP of 500
   watts at the following mountaintop sites: Palomar, Otay, Woodson and Miguel.
