The SO9I 6x2 Switch is designed for stations that need to share up to 6 antennas between 2 radios.
It is ideal for SO2R operation, multi-operator contest stations, and any shack where two radios are used interchangeably with several antennas. Instead of manually moving coaxial cables around, the 6x2 Switch allows each radio to select from the available antenna ports remotely using a separate Controller 6x2.
The switch uses two-colour LED indication, making it immediately clear which antenna is being used by which radio. Inside the unit, a mechanical lock physically prevents both radios from selecting the same antenna at the same time. This hardware safeguard helps protect your equipment by preventing accidental shared antenna selection.

How It Works
The SO9I 6x2 Switch allows two radios to share a bank of up to six antennas.
Each radio can select an antenna independently, while the switch’s internal mechanical locking system prevents both radios from being connected to the same antenna at the same time. This is handled in hardware, rather than relying on software, helping to keep the system robust and safe.
Two-Colour LED Indication
The switch features two-colour LED signalling, allowing you to see at a glance which antenna is currently selected and which radio is using it.
This is especially useful in contest, SO2R, and multi-operator environments where clear visual confirmation helps avoid mistakes.
Antenna Grounding
Unused antenna ports are automatically grounded. This helps reduce static build-up and provides an additional layer of protection for your station installation.
As with all antenna systems, this should not be considered a replacement for a properly designed grounding and lightning protection system.
