Call 0345 2300 599SO9I Outdoor 6×1 Switch
A rugged outdoor 6×1 remote antenna switch for locating the switching point close to your antennas, with stainless-steel construction, mast-mounting provision and high-power operation up to 4kW.
Outdoor Switch Only - Controller Required
This listing is for the SO9I Outdoor 6×1 remote antenna switch only. A separate SO9I Controller 6×1 is required for normal manual antenna selection.
The controller, control cable, U-bolt, coaxial cables, antennas and other station accessories are not included unless specifically stated otherwise.
Put the Switching Where It Makes Sense
For stations with several antennas on a roof, mast, tower or elsewhere around the property, bringing every individual feedline all the way back to the shack can quickly become cumbersome.
The SO9I Outdoor 6×1 Switch allows the switching point to be installed close to the antenna system. One common feedline runs back towards the station while up to six antennas are connected at the remote end.
A separate SO9I Controller 6×1 then allows the required antenna to be selected remotely from the operating position.
One Feedline. Up to Six Antennas.
Stainless-Steel Hood-Style Housing
The switch is enclosed in a stainless-steel housing shaped to act as a protective hood around the switching assembly.
Its shape encourages rainwater to drain away rather than collect on the enclosure, making the unit suitable for permanent outdoor installations close to the antennas.
Pre-Drilled for a U-Bolt
The housing includes pre-drilled mounting holes for a U-bolt, allowing the switch to be mounted directly to a suitable mast or support structure.
146 × 140 × 105mm
The compact enclosure keeps the remote switching installation neat while still providing six antenna ports and the common transceiver connection.
SO9I Controller 6×1
Manual operation requires the separately available SO9I Controller 6×1.
The controller remains in the shack and provides the six-position rotary selector used to command the remote switch, together with visual confirmation of the selected antenna.
Seven Wires Are All You Need
Communication between the switch and controller can be carried using standard twisted-pair cable.
Only seven conductors are required, avoiding the need for an expensive or specialised control cable between the shack and remote switch location.
LED at Every Antenna Port
Each antenna port has an LED showing which output is currently active. This provides a useful local indication during installation, testing and maintenance without needing to check the controller inside the shack.
Unused Antennas Are Grounded
Antenna ports that are not currently selected are automatically grounded by the switching system, helping discharge static build-up from unused antenna systems.
This provides useful additional protection, but it is not a replacement for a properly designed station earth, surge protection or lightning-protection system.
Built for High-Power RF
A reinforced copper layer on the PCB helps reduce heating and supports reliable operation at the switch's specified high-power rating.
Relays and Indication
The remote switch keeps the antenna-end electronics straightforward, concentrating on RF relays and local status indication rather than placing unnecessary control electronics outside.
Made to Live Close to the Antennas
