§ 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).
