Only a single feeding line per antenna/beam (for both the scanning and donor antenna systems) is required. Both the donor and scanning antenna system are connected to multiple individual coaxial cables each—one per antenna or beam. Power feed to each of the scanning antennas/beams is by a RF power switch circuitry (not shown, but disposed between the network analyser and the scanning antennas) comprising a timer. The timer of the switching circuitry is synchronized with the controller 506 such that the controller is able to ‘match’ information received from the RF network scanning analyser 504 to a particular scanning antenna/beam.

At the end of the first complete sequence pattern (i.e. after each of the three scanning antennas/beams has been operational for, for example, 20 seconds), the controller 506 analyses and compares the data received from the RF network scanning analyser 504 relating to the signals received from each antenna/beam to determine from which of the three antennas/beams the ‘best’ data was received. Determining which data is ‘best’ is based on predefined criteria. The criteria will depend on the specific circumstances of each implementation and the controller can be reconfigured accordingly. For example, the predefined criteria could comprise, solely, signal strength. The ‘best’ data will therefore be the strongest signal. The best data may be determine by an algorithm to take account of coverage, signal strength, available networks, etc.
