(under subclass 700) Subject matter including a tower or mast which transmits or receives radio waves; the tower or mast having structure which facilitates this transmission or reception of radio waves, or the tower or mast serving, in addition, as a support for other radio wave radiating or receiving structure.
(1) Note. A tower antenna herein comprises a metallic elongated structure of substantial height, generally of lattice type and constructed of component metallic elements such as I beams or girders, and is adapted to radiate or receive radiations of radio wave energy.
(2) Note. A mast antenna is usually a substantially solid, hollow, or built up pole-like element of metallic composition capable of radiation; and is distinguished from the rod type antennas of subclass 900 which are normally of negligible mass and relatively short, in that the masts of this subclass have appreciable weight and height and are adapted structurally to support such weight.
