Band 2 (67–116 GHz) is be offered on the 12-m Array starting from Cycle 13 (October 2026), with up to ~43 antennas depending on integration progress.

Initial capabilities are expected to include dual-polarization (total intensity) and on-axis polarization modes. The exact availability may still depend on technical readiness and operational constraints.
