Abstract
580,257. Aerial and like coupling- arrangements. STANDARD TELEPHONES & CABLES, Ltd. March 15, 1944, No. 4869. Convention date, Jan. 23, 1943. [Classes 40 (iii) and 40 (v)] A wide-band radiofrequency coupling between a stationary coaxial line 1 and an aligned rotatable coaxial line 2 is formed by expanding the outer conductor of each line and fitting the expanded portions 5, 6 one within the other to overlap for about a quarter wave-length ; one of the inner conductors 4 being also expanded for a quarter wave-length and fitted over the other inner conductor 3. A quarterwave shield 7 may be attached to the outer conductor of the line 1 and may extend a small distance into the opening between the expanded portions 5, 6 ; or it may lie outside the portion 6. The coupling may be used for connecting a radio transmitter or receiver to a rotatable aerial or goniometer.
