§  80.863   Antenna system.

   (a) An antenna system must be installed which is as nondirectional and
   as efficient as is practicable for the transmission and reception of
   radio ground waves over seawater. The installation and construction of
   the required antenna must insure operation in time of emergency.

   (b) If the required antenna is suspended between masts or other
   supports liable to whipping, a safety link which, under heavy stress,
   will operate to greatly reduce such stress without breakage of the
   antenna, the halyards, or other antenna-supporting elements, must be
   installed.

   (c) When an electrical ground connection is used as an element of the
   antenna system, the connection must be efficient.
