    (b) No CTS antenna shall be located within 61 m (200 feet) of a
residential dwelling unless the 218-219 MHz Service system licensee has
reduced power such that the field strength of the CTS antenna at the
residential dwelling does not increase relative to the field strength of
the CTS antenna at 61 m or obtained the written concurrence of the
resident(s) within 61 m of the CTS antenna. The written concurrence must
be kept as part of the 218-219 MHz Service system authorization.
    (c) The RTU may be connected to an external antenna not more than
6.1 m (20 feet) above ground or above an existing man-made structure
(other than an antenna structure). Connectors that are used to connect
RTUs to an external antenna shall not be of the types generally known as
``F-type'' or ``BNC type.'' Use of an external antenna is subject to
Sec. 95.861.
