CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION
PART 15_RADIO FREQUENCY DEVICES--Table of Contents
Subpart C_Intentional Radiators
Sec. 15.203 Antenna requirement.
An intentional radiator shall be designed to ensure that no antenna
other than that furnished by the responsible party shall be used with
the device. The use of a permanently attached antenna or of an antenna
that uses a unique coupling to the intentional radiator shall be
considered sufficient to comply with the provisions of this section. The
manufacturer may design the unit so that a broken antenna can be
replaced by the user, but the use of a standard antenna jack or
electrical connector is prohibited. This requirement does not apply to
carrier current devices or to devices operated under the provisions of
Sec. 15.211, Sec. 15.213, Sec. 15.217, Sec. 15.219, or Sec. 15.221.
Further, this requirement does not apply to intentional radiators that
must be professionally installed, such as perimeter protection systems
and some field disturbance sensors, or to other intentional radiators
which, in accordance with Sec. 15.31(d), must be measured at the
installation site. However, the installer shall be responsible for
ensuring that the proper antenna is employed so that the limits in this
part are not exceeded.
