                    CHAPTER I--FEDERAL COMMUNICATIONS

                         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.
