47 CFR 74.636 - Power limitations.

There are 3 Updates appearing in the Federal Register for 47 CFR 74. Select the tab below to view, or View eCFR (GPOAccess)
§ 74.636
Power limitations.
(a) On any authorized frequency, transmitter peak output power and the average power delivered to an antenna in this service must be the minimum amount of power necessary to carry out the communications desired and shall not exceed the values listed in the following table. Application of this principle includes, but is not to be limited to, requiring a licensee who replaces one or more of its antennas with larger antennas to reduce its antenna input power by an amount appropriate to compensate for the increased primary lobe gain of the replacement antenna(s). In no event shall the average equivalent isotropically radiated power (EIRP), as referenced to an isotropic radiator, exceed the values specified in the following table. In cases of harmful interference, the Commission may, after notice and opportunity for hearing, order a change in the effective radiated power of this station. The table follows:
Frequency band (MHz) Maximum allowable transmitter power Maximum allowable EIRP 2
Mobile (W) Fixed (dBW) Mobile (dBW)
2,025 to 2,110 12.0 45 35
2,450 to 2,483.5 12.0 45 35
6,425 to 6,525 12.0 35
6,875 to 7,125 12.0 55 35
12,700 to 13,250 1.5 55 45
17,700 to 18,600 55
18,600 to 18,800 1 35
18,800 to 19,700 55
1 The power delivered to the antenna is limited to −3 dBW.
2 Stations licensed based on an application filed before April 16, 2003, for EIRP values exceeding those specified above, may continue to operate indefinitely in accordance with the terms of their current authorizations, subject to periodic renewal.
(b) The EIRP of transmitters that use Automatic Transmitter Power Control (ATPC) shall not exceed the EIRP specified on the station authorization. The EIRP of non-ATPC transmitters shall be maintained as near as practicable to the EIRP specified on the station authorization.
