                       TITLE 47--TELECOMMUNICATION
                     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.
