Sec. 73.315 FM transmitter location.
(a) The transmitter location shall be chosen so that, on the basis of the
effective radiated power and antenna height above average terrain employed,
a minimum field strength of 70 dB above one uV/m (dBu), or 3.16 mV/m, will
be provided over the entire principal community to be served.
(b) The transmitter location should be chosen to maximize coverage to the
city of license while minimizing interference. This is normally accomplished
by locating in the least populated area available while maintaining the
provisions of paragraph (a) of this section. In general, the transmitting
antenna of a station should be located in the most sparsely populated area
available at the highest elevation available. The location of the antenna
should be so chosen that line-of-sight can be obtained from the antenna over
the principle city or cities to be served; in no event should there be a
major obstruction in this path.
(c) The transmitting location should be selected so that the 1 mV/m contour
encompasses the urban population within the area to be served. It is
recognized that topography, shape of the desired service area, and
population distribution may make the choice of a transmitter location
difficult. In such cases consideration may be given to the use of a
directional antenna system, although it is generally preferable to choose a
site where a nondirectional antenna may be employed.
(d) In cases of questionable antenna locations it is desirable to conduct
propagation tests to indicate the field strength expected in the principal
city or cities to be served and in other areas, particularly where severe
shadow problems may be expected. In considering applications proposing the
use of such locations, the Commission may require site tests to be made.
Such tests should include measurements made in accordance with the
measurement procedures described in Sec. 73.314, and full data thereon shall be
supplied to the Commission. The test transmitter should employ an antenna
having a height as close as possible to the proposed antenna height, using a
balloon or other support if necessary and feasible. Information concerning
the authorization of site tests may be obtained from the Commission upon
request.
(e) Cognizance must of course be taken regarding the possible hazard of the
proposed antenna structure to aviation and the proximity of the proposed
site to airports and airways. Procedures and standards with respect to the
Commission's consideration of proposed antenna structures which will serve
as a guide to persons intending to apply for radio station licenses are
contained in Part 17 of this chapter (Construction, Marking, and Lighting of
Antenna Structures).
