FCC 22.565 Revised as of October 1, 2007
Goto Year:2006 |

Sec. 22.565 Transmitting power limits.
The transmitting power of base, mobile and fixed transmitters operating on
the channels listed in Sec. 22.561 must not exceed the limits in this section.
(a) Maximum ERP. The effective radiated power (ERP) of base and fixed
transmitters must not exceed the applicable limits in this paragraph under
any circumstances.
Frequency range (MHz) Maximum ERP (watts)
152–153 1400
157–159 150
454–455 3500
459–460 150
(b) Basic power limit. Except as provided in paragraph (d) of this section,
the ERP of base transmitters must not exceed 500 Watts.
(c) Height-power limits. Except as provided in paragraph (d) of this
section, the ERP of base transmitters must not exceed the amount that would
result in an average distance to the service contour of 41.6 kilometers (26
miles) for VHF channels or 30.7 kilometers (19 miles) for UHF channels. The
average distance to the service contour is calculated by taking the
arithmetic mean of the distances determined using the procedures specified
in Sec. 22.567 for the eight cardinal radial directions, excluding cardinal
radial directions for which 90% or more of the distance so calculated is
over water.
(d) Encompassed interfering contour areas. Base transmitters are exempt from
the basic power and height-power limits of this section if the area within
their interfering contours is totally encompassed by the interfering
contours of operating co-channel based transmitters controlled by the same
licensee. For the purpose of this paragraph, operating transmitters are
authorized transmitters that are providing service to subscribers.
(e) Adjacent channel protection. The ERP of base and fixed transmitters must
not exceed 500 Watts if they transmit on channel 454.025 MHz and are located
less than 7 kilometers (4.3 miles) from any Private Radio Services station
receiving on adjacent channel 454.0000 MHz.
(f) Mobile transmitters. The transmitter output power of mobile transmitters
must not exceed 60 watts.
