(under subclass 793) Subject matter including two doublets as defined respectively in two of the subsequent subclasses 795, 801, 802, 803, 804, 805, 806, 808, 809, 811, and 823, or wherein two doublets each within the scope of subclass 793 above, have structurally different radiating masses to present significantly different electrical properties or radiation properties.
(1) Note. A mere difference in size with changed electrical or radiation properties normally following from such difference in size is not sufficient to constitute diverse type doublets within the definition.
(2) Note. Two groups of doublets, which doublets are in themselves not diverse in type but which groups have significantly different arrangements such as plural crossed or plural circumferentially arranged, are not classified in this subclass, but in the pertinent plural subclasses of doublets, below.
SEE OR SEARCH THIS CLASS, SUBCLASS:
724, for antennas convertible to different types of antennas, which may include conversion of one type of doublet to another type of doublet or from a doublet to another type of antenna.
726, and 727, for plural separate diverse type antennas which
include a doublet type antenna. 730, for plural separate diverse type antennas using the same active element including a doublet type antenna.
