Abstract: 275,631. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Beverage, H. H.). Aug. 3, 1926, [Convention date]. Coupling aeriaz and detecting circuits; fading, preventing.-When two. or more aerials are located at different distances from a common combining station, for instance for preventing fading effects, a retardation network is introduced into the line connecting the aerial system with the common receiver so as to preserve a uniform phase relation between the signal voltages, and an adjustable pick-up device is provided in order to maintain the desired phase relation when signals of different frequencies are being handled. As shown in Fig. 3, an artificial retardation line AL of known form is coupled through a transformer T1<SP>1> and amplifier C1 to the nearby aerial 1. The more distant aerial 2 is connected through an open transmission line TL to three amplifiers C2 associated with variable couplings M. A pickup coil Lp is common to the three secondary circuits and can be moved along the artificial line AL until the signal voltages from aerials 1 and 2 are in phase in the receivers R1, R2, R3. The manner of adjusting the position of the pickup coil Lp relatively to the inductances L of the retardation network so as to compensate for changes of line attenuation with signal frequency is shown in Fig. 2. The coil Lp is mounted on a track and is moved to and fro by means of a wire W, which is attached to a drum associated with a dial D. The artificial line may be built up of different numbers of sections according to the cut-off frequency desired. The relative signal intensities may also be controlled by introducing a potentiometer either in the longer line or in both lines. Fig. 6 shows three aerials 1, 2, 3 arranged in broadside formation and coupled to a common retardation line AL, the loading of which is graded so as to produce an apparently infinite phase velocity in the sections connecting the more distant receiving aerials.
