Abstract

The invention relates to a method of external antenna detection and an antenna detector for detecting if an external RF antenna is connected to a transmitter via an external antenna connector. A first low frequency electrical signal is applied to a first conductor of the antenna via the connector, sensing a second low frequency electrical signal on a second conductor of the antenna via the connector, and detecting if the external antenna is connected to the transmitter by comparing the first and second low frequency electrical signals. Preferably, the first low frequency electrical signal is a DC voltage. Preferably, an external antenna is detected to be connected to the transmitter if a magnitude of the second low frequency electrical signal exceeds a predetermined value. In addition, the invention relates to a consumption meter, such as a gas, heat, liquid, such as water, or electricity meter, with an antenna detector according to the described principle.
