Abstract

En anordning for å motta radiosignaler omfatter en mottager (25) som over forbindelseorganer (29) er tilkoblet en antenne (11).. Detektorutstyr (30) er anordnet for å påvise selektiv fading av nevnte radiosignaler samt for å samvirke med utstyr (28) for forskyvning av antennen (11) og innrettet for å utfare en slik antenneforskyvning at den selektive fading opphører. Anordningen er først og fremst beregnet for mottagere som befinner seg i kjøretøyer.
