                         COMMISSION (CONTINUED)
 
PART 21--DOMESTIC PUBLIC FIXED RADIO SERVICES--Table of Contents
 
                     Subpart C--Technical Standards
 
Sec. 21.117  Transmitter location.

    (a) The applicant shall determine, prior to filing an application 
for a radio station authorization, that the antenna site specified 
therein is adequate to render the service proposed. In cases of 
questionable antenna locations, it is desirable to conduct propagation 
tests to indicate the field intensity which may be expected in the 
principal areas or at the fixed points of communication to be served, 
particularly where severe shadow problems may be expected. In 
considering applications proposing the use of such locations, the 
Commission may require site survey tests to be made pursuant to a 
developmental authorization in the particular service concerned. In such 
cases, propagation tests should be conducted in accordance with 
recognized engineering methods and should be made with a transmitting 
antenna simulating, as near as possible, the proposed antenna 
installation. Full data obtained from such surveys and its analysis, 
including a description of the methods used and the name, address and 
qualifications of the engineer making the survey, must be supplied to 
the Commission.
    (b) The owner of the antenna structure should locate and construct 
such structure as to avoid making them hazardous to air navigation. (See 
part 17 of this chapter for provisions relating to antenna structures.) 
Such installation shall be maintained in good structural condition 
together with any required painting or lighting.
