| 摘要 |
The invention relates to an arrangement for measuring the condition of a receiver antenna at a base station, utilizing an antenna amplifier (15) positioned in connection with an antenna (6) apart from other base station equipments, e.g. at a mast. In the invention, a measuring signal is generated in connection (11) with the other base station equipments at a frequency outside the frequency band used for radio traffic and applied through an antenna line (7) to the antenna amplifier (15), in which the measuring signal is converted to the actual measuring frequency within the frequency band intended for the radio traffic. |
