Technical specifications:

micro STACK SWITCH� provides an optimum match for both two (2) and three (3) antenna stacks. micro STACK SWITCH� automatically recognizes the number of antennas and choose the appropriate matching.

"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.
