(under subclass 745) Subject matter wherein the active antenna is of the center-fed balanced doublet type as defined in subclass 793 below.
(1) Note. For classification in this subclass the variable reactance for tuning must be separate and distinct from the balanced doublet antenna. For example, balanced doublet antennas having an adjustable length whereby the inherent reactance of the antennas may be varied for tuning are classified in subclass 823, below.
SEE OR SEARCH THIS CLASS, SUBCLASS:
814, 816 and 820+, for balanced doublet type antennas with coupling networks which may include adjustable reactance elements.
823, for balanced doublet type antennas whose length is for tuning. See also (1) Note, above.
