Dual-Radio Remote Antenna Switching

SO9I 6×2 Remote Antenna Switch

Share up to six antennas between two independent radios, with high-power switching, hardware antenna-conflict protection and clear two-colour status indication.

Important

Switch Unit Only - Controller Required

This listing is for the SO9I 6×2 remote antenna switch only. A separate SO9I Controller 6×2 is required for normal manual operation.

The controller, control cable, coaxial cables, antennas, grounding accessories and other station equipment are not included unless specifically stated otherwise.

RADIOS
2 Radio Ports
Two transceivers can independently access the shared antenna bank.
ANTENNAS
Up to 6 Antennas
Share a single bank of six antennas between both operating positions.
POWER
Up to 4kW
High-power switching capability for demanding HF contest and station installations.
ISOLATION
>80dB
Excellent specified isolation between the R1 and R2 radio ports.
Two Radios. One Antenna System.

Built for SO2R and Multi-Operator Stations

The SO9I 6×2 Switch allows two separate transceivers to share a bank of up to six antennas without repeatedly moving coaxial cables around the shack.

Each radio can select its own available antenna through the separate Controller 6×2, making the system particularly well suited to SO2R, 2BSIQ and multi-operator contest stations.

It is equally useful in a home station where two different radios need flexible access to the same collection of HF antennas.

How It Works

Independent Antenna Selection for Two Radios

1. Connect Radio 1 The first transceiver connects to the R1 radio port.
2. Connect Radio 2 The second transceiver connects independently to R2.
3. Connect the Antennas Up to six antennas are connected to the shared antenna outputs.
4. Select Remotely Use the separate Controller 6×2 to allocate available antennas to either radio.
Hardware Conflict Protection

One Antenna Cannot Be Assigned to Both Radios

Inside the switch, a mechanical interlock prevents both radios from being connected to the same antenna at the same time.

This safeguard is handled in hardware rather than relying solely on software or operator procedure, helping prevent accidental shared antenna selection.

It provides an important additional layer of protection in a two-radio station, particularly where both transmitters may be active during contest or multi-operator operation.

RADIO-TO-RADIO ISOLATION

Greater Than 80dB

The specified isolation between the R1 and R2 ports is greater than 80dB, helping keep the two radio paths separated inside the switching system.

INSERTION LOSS

Less Than 0.1dB

Very low specified insertion loss helps keep additional loss through the remote switching system to a minimum.

Two-Colour Status Indication

See Which Radio Has Which Antenna

Two-colour LEDs provide immediate local indication of which antenna is selected and which radio is using it. This makes the live switching state easy to confirm during setup, maintenance and fast-paced contest operation.

Required Accessory

SO9I Controller 6×2

Manual operation requires the separately available SO9I Controller 6×2.

The controller provides two independent rotary selectors together with red and green LED indication, allowing each operating position to choose an available antenna from the shared six-port system.

Automatic Antenna Grounding

Unused Antenna Ports Are Grounded

Antenna ports that are not currently in use are automatically grounded by the switching system, helping discharge static build-up from unused antennas.

This provides useful additional protection, but should not be regarded as a substitute for a correctly designed station earth, surge protection or lightning-protection system.

HIGH-POWER DESIGN

Up to 4kW

The switching system is designed for high-power HF station use, with a stated maximum handling capability of 4kW.

REINFORCED PCB

Heavy Copper Construction

A reinforced copper layer on the PCB helps reduce heating and supports reliable operation in demanding high-power installations.

FREQUENCY
1-30MHz
IMPEDANCE
50Ω
MAXIMUM SWR

Construction

Substantial Desktop or Station Installation

The 6×2 switching system is housed in a 300 × 165 × 62mm black powder-coated enclosure with clear connection markings for the radio and antenna ports.

Ideal Applications

Made for Serious Multi-Radio Stations

SO2R Give two radios controlled access to a common antenna system.
2BSIQ Useful where two operating chains need rapid and clearly controlled antenna allocation.
Multi-Operator Share a common antenna bank between two operating positions.
Home Stations Ideal where two HF radios need flexible access to several antennas.
Please Note

Switch Unit Only

This product includes the SO9I 6×2 Remote Antenna Switch only. The SO9I Controller 6×2, control cable, coaxial cables, antennas, grounding equipment and other station accessories are sold separately unless specifically stated otherwise.
