A compact manual controller for the SO9I 6×2 remote antenna switch, giving two radios independent access to as many as six shared antennas with clear LED status indication and built-in conflict protection.
Controller Only - DB9 Control Cable Not Included
This listing is for the SO9I Controller 6×2 only. The SO9I 6×2 antenna switch, control cable, 12V power supply, coaxial cables and antennas are not included.
Connection to the remote switch is made using a standard DB9 control cable, so no specialised proprietary control lead is required.
Independent Antenna Selection from One Controller
The SO9I Controller 6×2 is the dedicated manual control unit for the SO9I 6×2 remote antenna switch.
Two independent rotary selectors allow each radio to choose from the connected antenna bank without having to swap coaxial cables or manually operate the remote switch.
Red and green status LEDs provide immediate visual confirmation of which antenna is currently allocated to each radio, making the system particularly useful in SO2R, contest and multi-operator stations.
One Selector for Each Radio
Red & Green LED Feedback
Two-colour indication makes it easy to see which antenna is allocated to each radio without having to remember the position of both selector knobs.
Simple One-of-Six Selection
Each rotary selector has six active antenna positions, allowing either radio to select any currently available antenna connected to the 6×2 switch.
"First Win" Antenna Allocation
A shared antenna must not be connected to both radios at the same time. The Controller 6×2 therefore incorporates a simple "first win" safeguard.
Whichever radio selects an antenna first retains control of that antenna. If the other radio attempts to select the same antenna while it is already allocated, it cannot take control until the first radio releases it.
This provides a straightforward hardware safeguard against accidental antenna conflicts during two-radio operation.
How "First Win" Works
D-Sub 9-Pin / DB9
The Controller 6×2 connects to the SO9I 6×2 antenna switch using a standard DB9 control cable.
The cable is not included, but the standardised connection means there is no requirement for a dedicated proprietary control lead.
Designed for Shack Integration
The controller operates from 12V DC and uses a 5.5/2.5mm DC power socket, making it straightforward to incorporate into a conventional amateur-radio station power system.
A Practical Solution for SO2R & Multi-Operator Setups
A 6×2 switching system allows two radios to share a common bank of antennas while still giving each operating position independent control.
This makes the Controller 6×2 particularly useful in SO2R, 2BSIQ and multi-operator stations, where antenna resources need to be shared without repeatedly moving coaxial connections.
SO9I-AS-6X2
The Controller 6×2 is designed for use with the SO9I-AS-6X2 Remote Antenna Switch, providing manual two-radio control of up to six shared antennas.
155 × 107 × 63mm
Compact enough to sit neatly between two operating positions or alongside the radios without taking up excessive desk space.
650g
The substantial desktop enclosure helps keep the controller stable while operating either rotary selector.
Controller Only
This product includes the SO9I Controller 6×2 only. The SO9I-AS-6X2 antenna switch, coaxial cables, DB9 control cable, 12V power supply, antennas and other station accessories are not included unless specifically stated otherwise.

Radio & Antenna Selection
Antenna Conflict Prevention
If one radio has already selected an antenna, the second radio cannot take control of that same antenna until it has been released by the first radio.
Control & Power
The controller is supplied without the control cable. A suitable standard DB9 lead is required between the Controller 6×2 and SO9I-AS-6X2 antenna switch.
