SKA-Low prototype stations

Caption

Aerial photographs show the two SKA-Low prototype stations: AAVS2 with its pseudo-random antenna arrangement (left) and AAVS3 with the Vogel "sunflower" layout (right). The Vogel pattern maximizes spacing between antennas to reduce interference, but on-sky tests revealed a sensitivity loss at 125 MHz that led the Observatory to select a different layout for the final telescope.
