Abstract

Foreliggende oppfinnelse angår en senderenhet for å sende radio- frekvenssignaler, og senderenheten omfatter: en inngang for å motta signaler som skal sendes, signalbehandlingsanordningerfor å overføre signaler som skal sendes, til et forutbestemt frekvensnivå, og en forsterker- anordning (2) for å forsterke og mate signaler som skal sendes til en antenneanordning i senderenheten. For å minimalisere effekttap omfatter antenneanordningen et antenneelement (ANT) som er festet med en festeanordning (3) til en forsterker (2) i antenneanordningen for å frem- sende radiosignaler som mates fra forsterkeren.The present invention relates to a transmitter unit for transmitting radio frequency signals, and the transmitter unit comprises: an input for receiving signals to be transmitted, signal processing means for transmitting signals to be transmitted to a predetermined frequency level, and an amplifier device (2) for amplifying and feeding signals to be transmitted to an antenna device in the transmitter unit. To minimize power loss, the antenna device comprises an antenna element (ANT) which is attached by a fastener (3) to an amplifier (2) in the antenna device to transmit radio signals fed from the amplifier.
