§  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
   § § 15.211, 15.213, 15.217, 15.219, 15.221, or § 15.236. 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 § 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.
