Dual-Radio Antenna Control

SO9I Controller 6×2

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.

Important

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.

RADIOS
2 Independent Radios
Each radio has its own rotary selector for independent antenna selection.
ANTENNAS
Up to 6 Antennas
Share a bank of up to six antennas between two operating positions.
STATUS
Red & Green LEDs
See at a glance which antenna is allocated to each radio.
PROTECTION
"First Win" Logic
Prevents both radios from accidentally being assigned to the same antenna.
Two Radios. Six Antennas.

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.

Independent Control

One Selector for Each Radio

Radio 1
Use the first rotary control to select the required antenna for the first transceiver.
Radio 2
Use the second rotary control independently to select an available antenna for the second transceiver.
STATUS INDICATION

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.

SIX ACTIVE POSITIONS

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.

Built-In Conflict Protection

"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.

Example

How "First Win" Works

1. Radio 1 Selects ANT 3 ANT 3 is allocated to Radio 1.
2. Radio 2 Selects ANT 3 The controller prevents Radio 2 from taking the antenna.
3. Radio 1 Releases ANT 3 ANT 3 becomes available for Radio 2 to select.
Standard Control Connection

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.

12V DC Operation

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.

Built for Two-Radio Stations

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.

Compatible Switch

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.

COMPACT

155 × 107 × 63mm

Compact enough to sit neatly between two operating positions or alongside the radios without taking up excessive desk space.

DESKTOP WEIGHT

650g

The substantial desktop enclosure helps keep the controller stable while operating either rotary selector.

Please Note

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.
