StackMaster II Controller, to make the antenna selection of a Stack of four antennas.
It takes care of the logic of selecting antenna ports from two StackMatches II that have two antennas each for a total of four. It has the option of using the StackMatch II Plus with a built-in a phase inverter to have the top pair and the bottom pair out of phase increasing the take off angle of the pattern in the vertical plane to improve communication with incoming high angle propagation like occurs with close-in stations.
Numerous combinations can be obtained with four antennas:
1234, 123, 234, 124, 134, 12, 34, 13, 14, 23, 24, 1, 2, 3 ,4
Which will produce an ample variety of take off angles for diversity and always have the optimal combination to receive the incoming signals. Added to this is the BIP/BOP (Both In Phase/Both Out Of Phase) for the bottom and top pairs.
