Sec. 22.165  Additional transmitters for existing systems.

    A licensee may operate additional transmitters at additional 
locations on the same channel or channel block as its existing system 
without obtaining prior Commission approval provided:
    (a) International coordination. The locations and/or technical 
parameters of the additional transmitters are such that individual 
coordination of the channel assignment(s) with a foreign administration, 
under applicable international agreements and rules in this part, is not 
required.
    (b) Antenna structure clearance required. For any construction or 
alteration that would exceed the requirements of Sec. 17.7 of this 
chapter, licensees must notify the appropriate Regional

[[Page 118]]

Office of the Federal Aviation Administration (FAA Form 7460-1) and file 
a request for antenna height clearance and obstruction marking and 
lighting specifications (FCC Form 854) with the FCC, PRB, Support 
Services Branch, Gettysburg, PA 17325.
    (c) Environmental. The additional transmitters must not have a 
significant environmental effect as defined by Secs. 1.1301 through 
1.1319 of this chapter.
    (d) Paging and Radiotelephone Service. The provisions in this 
paragraph apply for stations in the Paging and Radiotelephone Service.
    (1) The interfering contours of the additional transmitter(s) must 
be totally encompassed by the composite interfering contour of the 
existing station (or stations under common control of the applicant) on 
the same channel, except that this limitation does not apply to 
nationwide network paging stations or in-building radiation systems.
    (2) Additional transmitters in the 43 MHz frequency range operate 
under developmental authority, subject to the conditions set forth in 
Sec. 22.411.
    (3) The additional transmitters must not operate on control channels 
in the 72-76 MHz, 470-512 MHz, 928 MHz, 932 MHz, 941 MHz or 959 MHz 
frequency ranges.
    (e) Cellular Radiotelephone Service. During the five year build-out 
period, the service area boundaries of the additional transmitters, as 
calculated by the method set forth in Sec. 22.911(a), must remain within 
the market, except that the service area boundaries may extend beyond 
the market boundary into area that is part of the CGSA or is already 
encompassed by the service area boundaries of previously authorized 
facilities. After the five year build-out period, the service area 
boundaries of the additional transmitters, as calculated by the method 
set forth in Sec. 22.911(a), must remain within the CGSA. Licensees must 
notify the FCC (FCC Form 489) of any transmitters added under this 
section that cause a change in the CGSA boundary. The notification must 
include full size and reduced maps, and supporting engineering, as 
described in Sec. 22.953(a)(5) (i) through (iii). If the addition of 
transmitters involves a contract service area boundary (SAB) extension 
(see Sec. 22.912), the notification must include a statement as to 
whether the five year build-out period for the system on the relevant 
channel block in the market into which the SAB extends has elapsed, and 
whether the SAB extends into any unserved area in the market. The 
notification must be mailed or delivered to the filing place (see 
Sec. 22.106) no later than 15 days after the addition is made.
    (f) Air-ground Radiotelephone Service. Ground stations may be added 
to Commercial Aviation air-ground systems at previously established 
ground station locations, pursuant to Sec. 22.859, subject to compliance 
with the applicable technical rules. This section does not apply to 
General Aviation air-ground stations.
    (g) Rural Radiotelephone Service. A ``service area'' and 
``interfering contours'' must be determined using the same method as for 
stations in the Paging and Radiotelephone Service. The service area and 
interfering contours so determined for the additional transmitter(s) 
must be totally encompassed by the similarly determined composite 
service area contour and predicted interfering contour, respectively, of 
the existing station on the same channel. This section does not apply to 
Basic Exchange Telecommunications Radio Systems.
    (h) Offshore Radiotelephone Service. This section does not apply to 
stations in the Offshore Radiotelephone Service.
    (i) Provision of information upon request. Upon request by the FCC, 
licensees must supply administrative or technical information concerning 
the additional transmitters. At the time transmitters are added pursuant 
to this section, licensees must make a record of the pertinent technical 
and administrative information so that such information is readily 
available. See Sec. 22.303.
