DEFINITION

Classification: 343/907

(under subclass 700) Components and elements not constituting a complete antenna which are limited to use in antennas and which are not provided for in any preceding subclass or in any other class.

(1) Note. This subclass includes antenna conductors under the class definition which involve the material or composition of the conductor and which conductors are not classifiable in any other class.

(2) Note. This subclass does not provide for the antenna conductor defined only as being formed of a particular composition or material, or only as a base with a coating or lamination thereon. For the excluded subject matter, see SEARCH CLASS below.

(3) Note. This subclass does not provide for antenna conductors which are defined only as a wire or electric conductor. For the excluded subject matter, see SEARCH CLASS below.
