DEFINITION

Classification: 343/803

(under subclass 793) Subject matter wherein the two active conductive masses include elongated conductors which extend outwardly from the antenna lead in terminals together with an additional elongated conductor or conductors extending along the length of and close to the first conductors to form a transmission line therewith, the first and second conductors being joined at the outer ends as by bending to present a substantially increased radiation resistance at the antenna lead in terminals.

(1) Note. While folded dipoles may form a closed circuit as do the high frequency loops in subclass 741 above, the conductors of the folded dipole are close together to form a transmission line, whereas the conductors of the high frequency loop are spaced further apart so that the closed circuit encloses a relatively larger area.

741, for high frequency type loops. See also (1) Note, above.
