Call 0345 2300 599SO9I Controller 6×1
A compact manual controller for SO9I 6×1 remote antenna switches, giving you fast six-position antenna selection and clear front-panel confirmation directly from the operating desk.
Controller Only - DB9 Control Cable Not Included
This listing is for the SO9I Controller 6×1 only. The antenna switch, control cable, power supply, coaxial cables and antennas are not included.
Connection to the antenna switch is made using a standard DB9 control cable, so no proprietary or specialised controller lead is required.
Choose the Antenna Without Leaving the Shack
The SO9I Controller 6×1 is designed to operate SO9I's remotely mounted 6×1 antenna switches, allowing one transceiver or feedline to select between as many as six antennas.
Instead of manually changing coaxial cables or walking outside to operate a switch, simply turn the selector on the desktop controller to the antenna you want.
Front-panel LED indication provides an immediate visual check of the selected position, helping keep operation simple and unambiguous.
Straightforward One-of-Six Selection
Instant Antenna Selection
The controller uses an eight-position rotary switch, with six positions used for antenna selection. Turn the knob to the required antenna and the connected SO9I switch changes to the corresponding port.
Clear Position Confirmation
The front-panel indication gives you a clear visual check of the selected antenna position, removing uncertainty about whether the remote switch has changed as intended.
Standard DB9 Cable - No Proprietary Lead
The controller connects to the antenna switch through its D-Sub 9-pin socket using a standard DB9 control cable.
The control cable is not included, but the use of a standard connection means there is no need for a dedicated proprietary SO9I cable.
Easy to Integrate into the Shack
Power is supplied from 12V DC through a 5.5/2.5mm DC socket, making the Controller 6×1 straightforward to incorporate into a typical amateur-radio station power system.
Two Controllers Can Operate a 6×2 Switch
Two Controller 6×1 units can be used together to operate an SO9I 6×2 antenna switch.
This can be useful if you already own a Controller 6×1 and later expand to a two-radio antenna system, or if you simply prefer separate physical controllers for each radio.
