Beschreibung
Zusammenfassung:	The invention relates to an apparatus integrated in a wind turbine blade for establishing the distance X between a root antenna and a tip antenna, the apparatus comprising: a root antenna mounted at a root portion of the blade, a tip antenna mounted at the tip portion of the blade, a signal transmitter connected to one of the tip or root antennas, a signal receiver connected to the other of the tip or root antennas, and a data processing unit configured to control transmittal of a radio signal via the signal transmitter and processing of the radio signal received by the signal receiver, wherein the data processing unit, signal transmitter and signal receiver are located inside the wind turbine blade, wherein the processing of the radio signal results in determining a peak value of the received signal, and wherein the distance X is established based on the determined peak value.
