Abstract (en)

[origin: EP3406502A1] A balise to be arranged between the two rails of a railway track has a transmitter loop (5) surrounding a receiver loop (2). The transmitter loop has at at least one location along the extension thereof at least one extra turn (11, 12), which encloses an area being a fraction of the area enclosed by the transmitter loop and is designed to have a current (I t ) flowing through the transmitter loop running through the extra turn while generating a magnetic field felt by the receiver loop being opposed to a magnetic field felt by the receiver loop through the current running through the part of the transmitter loop not belonging to a said extra turn (11, 12).
