DEFINITION

Classification: 343/763

(under subclass 757) Subject matter wherein the antenna is rotatably supported together with structure for imparting continuous or oscillating angular motion to the complete antenna as a unit relative to its support.

(1) Note. When means for rotating the antenna is a hand operated control level or linkage system and the antenna is claimed by name only classification is elsewhere (see the Search Class notes below); otherwise (when antenna details are claimed), classification is herein.

(2) Note. For classification in this or indented subclasses the claimed combination of the antenna and the means to impart rotary motion thereto must include detailed antenna structure as opposed to the mere recitation of an antenna or reflector by name only. In the latter case classification is with the type of combination claimed for imparting motion (see the Search Class notes below).
