Stack Match 1-3 MP INVERTED
OLDER VERSION - new and fully functional device with THT components
224.00 € (without tax)
This stack match 1-3 is designed for impedance match two or three antennas (PA) to one TRX. All outputs are in phase. You can match two or three antennas at the same tower or use it as a Multi Beaming - antennas to different directions. It will provide the user with all combinations of antenna selection. Could be controlled independently for RX and TX (depends on controller). This Stack Match works with Mono-band antennas as well as Tri-band and Multi-band antennas!
Inverted means that all 3 ports including the transformer are connected without supply voltage. The control voltage disconnects the individual ports.
Using
- Three outputs from one input

Parameters
- Low insertion loss
- Impedance matching compromise for 2 or 3 antennas
- Frequency range: 1.8 MHz to 30 MHz
- Power rating MP < 3kW and HP < 5kW. Normal CW, SSB, RTTY DX operation. In contest mode: CW, SSB 75% and RTTY 50% of HF power
Control
Without control voltage applied, all three ports (1, 2, 3) and the transformer are connected. If you want to change combinations, the control works in the opposite way to our classic Stack Match. The supply voltage disconnects the ports we don't want to use, as well as the transformer.
- ANT 1 + ANT 2 + ANT 3 = no control voltage
- ANT 1 = 13.8V to A2, A3, Tr
- ANT 2 = 13.8V to A1, A3, Tr
- ANT 3 = 13.8V to A1, A2, Tr
- ANT 1 + ANT 2 = 13.8V to A3
- ANT 1 + ANT 3 = 13.8V to A1
- ANT 2 + ANT 3 = 13.8V to A1
- NO ANT = 13.8V to A1, A2, A3, Tr
