Remote 6×1 Antenna Switching

SO9I Standard 6×1 Switch

Connect up to six antennas to a single transceiver and select the one you need remotely from the shack, without repeatedly disconnecting and moving coaxial cables.

Important

Switch Unit Only - Controller Required

This listing is for the SO9I Standard 6×1 remote antenna switch only. A separate SO9I Controller 6×1 is required for normal manual operation.

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

ANTENNAS
6 Outputs
Connect up to six antennas to a single transceiver or station feedline.
POWER
Up to 4kW
Heavy-duty switching design for high-power HF amateur-radio installations.
FREQUENCY
1-50MHz
Designed for HF operation through to the lower edge of the 6m amateur band.
PROTECTION
Unused Ports Grounded
Unselected antenna ports are automatically grounded to help reduce static build-up.
One Radio. Six Antennas.

Stop Swapping Coax by Hand

A station with several antennas quickly becomes awkward if every change means reaching behind the transceiver or physically swapping feedlines.

The SO9I Standard 6×1 Switch solves that problem by placing the antenna switching remotely and allowing a single transceiver to select any one of up to six connected antennas.

Used with the separate SO9I Controller 6×1, antenna selection becomes a simple turn of a rotary control from the operating desk.

How It Works

Remote Selection from the Shack

1. Connect the Radio Connect the station feedline to the common radio port.
2. Connect Up to Six Antennas Each antenna connects to its own switched output.
3. Connect the Controller Run a suitable twisted-pair control cable back to the shack.
4. Select the Antenna Use the Controller 6×1 to choose the required output remotely.
Required Accessory

SO9I Controller 6×1

Manual antenna selection is provided by the separately available SO9I Controller 6×1.

The desktop controller provides a six-position rotary selector and confirmation indication, allowing the remote switch to remain close to the antennas while the actual selection is made conveniently from the shack.

SIMPLE SWITCHING UNIT

Relays and Status LEDs

SO9I deliberately keeps the remote switching unit straightforward. The antenna end contains the switching relays and indication LEDs rather than a complete control computer, reducing unnecessary complexity.

REINFORCED PCB

Built for High-Power RF

A reinforced copper layer on the PCB is used to reduce heating and support reliable operation at the switch's specified maximum power level.

Port Indication

LED at Every Antenna Port

Each antenna connection has its own LED indication, allowing the selected output to be identified directly at the switch during installation, testing or maintenance.

Automatic Antenna Grounding

Unused Antennas Are Grounded

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

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

Simple Control Wiring

Standard Twisted-Pair Cable

Communication between the switch and separate Controller 6×1 can be carried over standard twisted-pair computer cable, avoiding the need to run an expensive proprietary multicore control lead between the shack and antenna installation.

FREQUENCY
1-50MHz
IMPEDANCE

Construction

Compact Powder-Coated Housing

The switching system is housed in a compact 180 × 148 × 45mm enclosure with a black powder-coated finish and clearly marked antenna connections.

Please Note

Switch Only
