"Out of phase" stacks can be created by installing a (selectable) 180 degree (half wavelength) 50 ohm coax line for single band stacks or a broadband 180 degree transformer for multiband stacks between the WL/2 connectors.  "BOP" combinations are available using ANT 1 & ANT 2 or ANT 2 & ANT 3 as well as "middle out of phase" for the three antenna stack.  With no power applied, antennas 1, 2 and 3 are in phase.
