Abstract
581,667. Aerial coupling arrangements. STANDARD TELEPHONES & CABLES, Ltd. Oct. 6, 1944, No. 19244. Convention date, Jan. 31. [Class 40 (v)] A balanced circuit 29 is coupled to an unbalanced circuit, such as an aerial 29A, through two equal sections of coaxial line 22, 24 and 23, 25 arranged parallel to each other, the circuit 29 being connected between the inner conductors 22, 23 at one end and the circuit 29A being connected at the other end to connections 26, 27 between the inner conductor of each section and the outer conductor of the other section. At the end 29 the outer conductors are earthed and the inner conductors connected to earth through equal resistances 20, 21. Radiation from the outer conductors, which are less than a quarter wavelength long at the working frequency, is minimised by spacing them by a distance not greater than one tenth and preferably less than the seventieth of their length. In another embodiment (Fig. 3, not shown), an asymmetric valve output circuit is coupled to a. pair of symmetrically arranged, but separate, aerials. In all cases the source and load can be interchanged.
