(under subclass 731) Subject matter wherein the elongated conducting mass forms substantially a circle in a single plane.
(1) Note. Helical traveling wave type antennas are not classified in this subclass since any single loop turn does not lie in a single plane, but are classified in subclass 731 above. A plurality of traveling wave type antennas whose respective active portions are arranged end to end to form a circle are not classified herein but in subclass 737, below.
SEE OR SEARCH THIS CLASS, SUBCLASS:
741+, for high frequency type loops which do not operate on the traveling wave principle.
866+, for loop type antennas in general which do not operate on the traveling wave principle.
