§ 74.733 UHF translator signal boosters.
(a) The licensee of a UHF television broadcast translator station may
be 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 § 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 § § 74.767 and 74.781 concerning marking and
lighting of antenna structures and station records, respectively, apply
to UHF translator signal boosters.
