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.
