This is two port antenna switch - middle box between pair of Bi-Directional antennas with single coax output.
K9AY/4-WAY Antenna Switch Controller
This is antenna controller for K9AY and Bi-directional beverages. You can use DC control wires as well as AC/DC voltage over the coax to antenna. There are Band Pass Filters and preamplifier directly in the controller. Including RX protections and front panel switch between RX and TX antenna.

This is universal controller for 4 directional RX antenna. You can control directions of antenna by DC voltage or you can use internal Bias Tee and apply AC/DC voltage to RX antenna coax. Jumpers inside allow you to set right voltage combinations. There are front end protections, HPF for AC noise blocking, three Band Pass Filters, Preamplifier and RX way switch. Thanks to this switch, you can use RX antennas with any TRX - you do not need RX ANT IN connector at your TRX. Rload knob changes DC voltage from about 6 to 1.5 V and you can use it with K9AY feeder and change loop termination resistance. Version REMOTE has got also possibility to control these features by the external controller.
Main functions
- Universal box for K9AY or 4-way Bi-Dir beverage system - front panel image

- POWER SUPPLY MUST BE 12V AC not DC
- SMD + THT construction
- REMOTE version - LED indicator LOCAL/REMOTE - image
- Stainless screws and nuts
- High quality connectors
- DC plug included
- ASSEMBLED and TESTED VERSION
Remote Control Notes
- There is NO IP/web based remote control inside the box. RJ45 connector is only for DC voltage between controller and feeder. Remote Control can be done by the DB15M connector at the rear panel. When you apply +12 to +14 V DC to direction pin at this connector, relay automatically deactivate front panel switches and you can control it over these external voltages at DB-15M Remote Control connector. All LED indicators still work. Please, read the manual.
- We are preparing new universal web based controller not only for K9AY++. Coming soon ODKAZ.
