Antenna 3 was in the hall during the second part of June for major maintenance (specially on the boggies of the transporter), and has now been replaced in the hall by Antenna 2. Lighter maintenance will be done on antenna 4 by the end of July. Antenna 1 also requires a major maintenance. This will include a new equipment for the control of the antenna transport, which will be interfaced with the VME computer as in antenna 5. This equipment requires major re-cabling (2-3 weeks of work). Antennas 2-3-4 will be similarly upgraded next year.
