DEFINITION
Classification: 343/856
(under subclass 850) Subject matter wherein the active antenna forms the secondary or primary winding of a transformer magnetically coupled from a primary or to a secondary winding for connecting from or to a signal source or receiver, respectively.
(1) Note. A mere transformer winding in series with the antenna is not sufficient for such subject matter to be classified herein. The portion of the antenna which directly radiates or receives the radiant signal energy itself must form a substantial portion of the primary or secondary winding involved in the coupling to or from a signal receiver or source to be classified herein.

857, for antennas having coupling to spaced points thereon wherein such coupling may be by transformer means.
866+, for loop type antennas.
