Реферат: An aerial system which is used for determining the exact position of road vehicles forming part of a transport network. The system cuts out the negative effects of the approximately constant field strengths. The aerial system (1, 1') consists of two or more separate aerials or elements which are interlinked. They compensate the constant field components of the signals received along a leakage cable (3). The preferred signal components received are those which change in the direction based on the periodicity of the slotted sequence of the leakage cable. The distance between the individual aerial elements are equivalent to half the periodicity of an uneven multiple of the slots sequence of the leakage cable.
