MWA Phase II is the upgraded array deployed in 2016-2017. It consists of 128 new tiles divided into two new subsets:
- 72 tiles in two compact hexagons near the core for improved EoR capabilities
- 56 tiles on extended baselines up to 5 km, for improved survey and imaging capabilities
Note that only 128 tiles will be available for correlation at any time during MWA Phase II.
You can find the coordinates of the tiles in the compact array here.

You can find the proposed coordinates of the tiles in the extended array here. Note that the actual coordinates of the extended tiles may change slightly during deployment.
