§ 22.659   Effective radiated power limits.

   The purpose of the rules in this section, which limit effective radiated
   power (ERP), is to reduce the likelihood that interference to television
   reception from public mobile operations on these channels will occur. The
   protected TV station locations specified in this section are the locations
   of record as of September 1974, and these do not change even though the TV
   stations may have been subsequently relocated.

   (a) Maximum ERP. The ERP of base transmitters must not exceed 100 Watts
   under any circumstances. The ERP of mobile transmitters must not exceed 60
   Watts under any circumstances.

   (b)  Co-channel  protection  from  base  transmitters. The ERP of base
   transmitters in the New York-Northeastern New Jersey urban area must not
   exceed the limits in the tables referenced in paragraphs (b)(2) and (b)(3)
   of this section. The limits depend upon the height above average terrain of
   the base transmitter antenna and the distance between the base transmitter
   and the nearest protected TV station location in paragraph (b)(1) of this
   section.

   (1) The protected TV station locations are as follows (all coordinates are
   referenced to North American Datum 1983 (NAD83)):
   Control transmitter frequency range Protected TV station location
   470-476 MHz Washington, DC, 38°57′17.4″ N. Lat. 77°00′15.9″ W. Long.
   476-482 MHz Lancaster, PA, 40°15′45.3″ N. Lat. 76°27′47.9″ W. Long.

   (2) Tables E-8 and E-9 of this section apply to base transmitters in the New
   York-Northeastern New Jersey urban area that transmit on channels in the
   476-482 MHz range.

   (3) Tables E-10 and E-11 of this section apply to base transmitters in the
   New York-Northeastern New Jersey urban area that transmit on channels in the
   470-476 MHz range.

   (c) Adjacent channel protection from base transmitters. The ERP of base
   transmitters must not exceed the limits in Table E-12 of this section. The
   limits depend upon the height above average terrain of the base transmitter
   antenna  and the distance between the base transmitter and the nearest
   protected TV station location specified in paragraph (c)(1) of this section.

   (1) The protected TV station locations are as follows (all coordinates are
   referenced to North American Datum 1983 (NAD83)):
   Control transmitter frequency range Protected TV station location TV channel
   470-476 MHz Hanover, NH, 43°42′30.3″ N. Lat. 72°09′14.3″ W. Long (15)
   476-482 MHz
   482-488 MHz Lancaster, PA, 40°15′45.3″ N. Lat. 76°27′47.9″ W. Long (15)
       Scranton, PA, 41°10′58.3″ N. Lat. 75°52′19.7″ W. Long (16)
       Hanover, NH, 43°42′30.3″ N. Lat. 72°09′14.3″ W. Long (15)

   Note: Coordinates are referenced to North American Datum 1983 (NAD83).

   (2) Table E-12 of this section applies to base transmitters in the New
   York-Northeastern New Jersey urban area.

   See § 22.659(b)(2). This table is for antenna heights of 152 meters (500
   feet) or less above average terrain. For antenna heights between those in
   the table, use the next higher antenna height. For distances between those
   in the table, use the next lower distance.
