First light 2nd Proto LOFAR HBA

Submitter: Henri Meulman
Description: First light 2nd Proto LOFAR HBA

On the test field at ASTRON the HBA-team did set up 16 High Band Antenna’s (one tile) of the 4 tiles witch will be placed soon after. After the first proto type, placed last year, and a 4-tile version at Westerbork, a lot has been changed at the design and performance. All functionality s.a. beamforming and amplification of the received signals will be performed by the electronics inside the antenna, instead of in a large complex external board. Power and serial communication will be supplied to the antennas via the same two coaxial cables witch are used for receiving the two RF signals (X and Y polarization).
Last week the antennas were switched on successfully for the first time. In the coming weeks more tests will be done.
