Antenna one to three STACK MATCH by OK2ZAW

Stack Match 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!

Main functions:

• Three outputs to one input.
• High quality PCB 2mm
• Own cores with low loss.
• QRO64-61 for power up to 3kW.
• QRO64-2D-61 for power up to 5kW. Cores link
• Connectors PL-259, N or 7/16 female with gold plated.
• High quality ATC RF capacitors
• Power consumption < 3W.
• Aluminium shield enclosure.
• Aluminium mounting holder with bracket.
• Size 190 x 120 x 150 mm
• Weight 1.4 kg

*) Normal CW, SSB, RTTY DX operation. In contest mode: CW, SSB 75% and RTTY 50% of HF power.

**) Please specify during the order. We can optimalise transformer for low bands, high bands or 6m.
