§ 22.535   Effective radiated power limits.

   The effective radiated power (ERP) of transmitters operating on the channels
   listed in § 22.531 must not exceed the limits in this section.

   (a) Maximum ERP. The ERP must not exceed the applicable limits in this
   paragraph under any circumstances.
   Frequency range (MHz) Maximum ERP (Watts)
   35-36                                 600
   43-44                                 500
   152-159                              1400
   931-932                              3500

   (b) Basic power limit. Except as provided in paragraph (d) of this section,
   the ERP of transmitters on the VHF channels must not exceed 500 Watts.

   (c) Height-power limit. Except as provided in paragraph (d) of this section,
   the ERP of transmitters on the VHF channels must not exceed the amount that
   would  result  in  an  average distance to the service contour of 32.2
   kilometers  (20 miles). The average distance to the service contour is
   calculated by taking the arithmetic mean of the distances determined using
   the  procedures  specified  in  § 22.537  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. 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 base 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 transmitters must not exceed 500
   Watts if they:

   (1) Transmit on a channel in the 152-159 MHz frequency range and are located
   less than 5 kilometers (3.1 miles) from any station licensed in the Private
   Radio Services that receives on an adjacent channel; or,

   (2) Transmit on channel 158.10 or 158.70 MHz and are located less than 5
   kilometers  (3.1 miles) from any station licensed in the Public Mobile
   Services that receives on either of the following adjacent channels: 158.07
   MHz or 158.67 MHz.

   (f) Signal boosters. The effective radiated power of signal boosters must
   not exceed 5 watts ERP under any normal operating condition.
