(under subclass 866) Subject matter including a plurality of distinct coils or windings, or including one or more taps on a coil or winding to vary the effective number of coil or winding turns; or including a plurality of loop type antennas as defined in subclass 866 above.
(1) Note. A coil or winding is composed of one or more turns of an electrical conductor. In a plurality of such coils or windings there is also one or more turns of an electrical conductor, but there is a discontinuity in the turns to establish discrete groups or sets of turns.
