Abstract

An arrangement (102, 100) for monitoring the operation of a transmitter antenna system (112). The transmitter antenna system is adapted for the emission of one or more information signals (M1.1 , M2.1 , M3.1 , M4.1). The arrangement for monitoring is provided with a retrieval arrangement (102) for retrieving a first detection signal which is a measure for the reflection signal in the transmitter antenna system. According to the invention, the arrangement for monitoring is further provided with a detection arrangement (100) which is adapted to establish whether, in the frequency characteristic of the first detection signal, frequency components that are different from the one or more information signals (M1.1 , M2.1 , M3.1 , M4.1) are present in the first detection signal and to generate a second detection signal if this is the case. This way, the occurrence of an arc in a transmitter antenna system can be reliably established.
