Universal control box for receiving antenna such as K9AY and bi-directional Beverage. The control box provides directional switching with LED indication - four directions with N-S-E-W or NW-NE-SE-SW options. Potentiometer to control output voltage for the ability to change load resistance - Rload. BPD for 160, 80 and 40m bands, high dynamic range preamplifier with gain control. Switch to select listening from TX or RX antenna. Built-in bias tee for sending voltage over coaxial cable or DC voltage from rear panel connectors.
The control box allows a remote control unit to be connected for remote control. When in remote control mode, the front panel controls are disabled, but the LED indicator remains active.
Built-in 100 kHz HPFs that eliminate the problem of AC voltage being used to switch directions over the coaxial cable.
Main functions
- Universal box for K9AY or 4-way Bi-Dir beverage system - front panel image
- 4-way beverage system can have 4 construction positions in the field - more info in manual
- FOUR direction control
- Control via coax or DC cable

- HPF > 100 kHz as AC noise eliminator (80 dB at 20 kHz)
- Front End protections
- RF power limiters in RX line
- LED direction indicator 0 or 45 deg. - image
- Three BPFs and Bypass - 4 positions switch on the front panel
- Load resistor (Rload) potentiometer at front panel
- Different Rload for remote control - by band - manual
- High dynamic preamplifier with gain control

- Preamplifier switch and LED indicator
- POWER SUPPLY MUST BE 12V AC for control over the coax
- 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.
- Please, have a look at our Remote controllers - blog post Remote System.
- We offer now two IP controllers: OLI IP 12 and powerful REMOTIUS 64.

Remote Control example
We offer two web-based controllers. OLI IP 12, which is directly designed for K9AY++, 4-WAY and 7ANT RC controllers and REMOTIUS 64, bigger controller which could control more parts and offers more outputs.
There is more ways for remote control:
- Classic UI
- Beam Map
- Stream Deck, NodeRed or custom system
Option: Common-mode current choke to ham shack
