Abstract
An antenna system is disclosed herein which includes a frontend portion, a backend portion and a feed line which connects frontend portion and backend portion with each other. The frontend portion comprises at least two antennas, a combiner connected downstream of the antennas and upstream of the feed line and antenna connectors that electrically connect through antenna plugs, the antennas to the combiner. The backend portion includes an electrical power source connected to the feed line and a resistance evaluation circuit connected between the electrical power source and the feed line and that measures the resistance of the frontend portion through the feed line. At least one of the antenna connectors is in mechanical contact with a jumper having jumper plugs between which a high resistance connection and a low resistance connection is provided that depends on whether the corresponding antenna is connected to the combiner or not.
