Technical specifications:
 
micro SSTACK SWITCH� contains a unique matching circuit that includes a separate antenna match for two (2) and for the three (3) antennas.  micro STACK SWITCH� automatically recognizes the number of antennas in use and selects the appropriate match maintaining optimum loading for the power amplifier. 
 
Out of phase (BOP) stacks may be created by connecting a half wavelength of 50 ohm coax (for single band stacks) or a broadband phase reversing transformer (for multiband stacks) between the WL/2 connectors.  Two BOP combinations are available: between ANT 1 & ANT 2 or ANT 2 & ANT 3.  With three antennas selected, "middle out of phase" is also available.
 
With no power applied, antennas 1, 2 and 3 are in phase.
