Sec. 74.733  UHF translator signal boosters.

    (a) The licensee of a UHF television broadcast translator station 
may be

[[Page 436]]

authorized to operate one or more signal boosters for the purpose of 
providing reception to small shadowed areas within the area intended to 
be served by the translator.
    (b) The transmitting apparatus shall consist of a simple linear 
radio frequency amplifier, with one or more amplifying stages, which is 
capable of receiving, amplifying, and retransmitting the signals of the 
parent translator without significantly altering any electrical 
characteristic of the received signal other than its amplitude. The 
maximum power input to the plate of the final radio frequency amplifier 
shall not exceed 5 watts.
    (c) The amplifier shall be equipped with suitable circuits which 
will automatically cause it to cease radiating if no signal is being 
received from the parent translator station. Care shall be taken in the 
design of the apparatus to insure that out-of-band radiation is not 
excessive and that adequate isolation is maintained between the input 
and output circuits to prevent unstable operation.
    (d) The installation of the apparatus and its associated receiving 
and transmitting antennas shall be in accordance with accepted 
principles of good engineering practice. Either horizontal, vertical, or 
circular polarization of the electric field of the radiated signal may 
be employed. If the isolation between the input and output circuits 
depends in part upon the polarization or directive properties of the 
transmitting and receiving antennas, the installation shall be 
sufficiently rugged to withstand the normal hazards of the environment.
    (e) The operation of a UHF translator signal booster is subject to 
the condition that no harmful interference is caused to the reception of 
any station, broadcast or non-broadcast, other than the parent 
translator. The licensee of the UHF translator signal booster is 
expected to use reasonable diligence to minimize interference to the 
direct reception of the parent translator station.
    (f) UHF translator signal boosters may be operated unattended. 
Repairs and adjustments shall be made by a qualified person. The 
required qualifications are set forth in Sec. 74.750 (g) and (h).
    (g) An individual call sign will not be assigned to a UHF translator 
booster station. The retransmission of the call sign of the parent 
translator will serve as station identification.
    (h) Applications for authority to construct and operate a UHF 
translator signal booster shall be submitted on FCC Form 346A. No 
construction of facilities or installation of apparatus at the proposed 
transmitter site shall be made until a construction permit therefor has 
been issued by the Commission.
    (i) The provisions of Sec. 74.765 concerning posting of station 
license shall apply to a UHF translator signal booster except that the 
parent UHF translator call sign, followed by the word ``Booster'', shall 
be displayed at the signal booster site.
    (j) The provisions of Secs. 74.767 and 74.781 concerning marking and 
lighting of antenna structures and station records, respectively, apply 
to UHF translator signal boosters.

    Note: Effective July 11, 1975, no new UHF signal boosters will be 
authorized. Licensees of such existing boosters may make application for 
renewal of license or change in facilities on the applicable FCC forms 
for Television Broadcast Translator Stations (Form 346, for construction 
permits; 347, for license to cover construction permit; and 303-S, for 
renewal of license). Report and Order, Docket No. 20372. May 28, .
