Antenna one to three STACK MATCH by OK2ZAW

StackMatch is designed to stack, match and power split to one,
two or three antennas or to split driving power into more PAs for the multibeaming.
It will provide the user with all combinations of antenna selection.
Could be controlled independently for RX and TX - depends on controller.
Works with Mono-band antennas as well as Tri-band and Multi-band antennas!
