The Triax TOU-4 is a TV and radio wall outlet for households with their own antenna and installations with several outlets connected in series. Separate TV and FM radio connections allow both devices to be connected at the same location.
Connections for incoming and outgoing antenna cables allow the signal to continue to the next outlet. This makes the TOU-4 a practical choice for extending or upgrading an existing antenna installation.
Its die-cast aluminium construction and standard IEC connectors provide a robust outlet for permanent installation. It can be flush-mounted in a round Ø60 mm wall box or surface-mounted using a TOU frame.
The product is supplied without a cover plate or termination resistor. When used as the final outlet in a series, its output must be terminated with a 75-ohm termination resistor.
✅ Product Benefits
- Separate TV and FM connections on one outlet.
- Cable input and output for connection to the next outlet.
- Suitable for households with their own antenna.
- Practical for multiple outlets connected in series.
- Robust die-cast aluminium construction.
- Standard IEC connectors.
- Fits a round Ø60 mm wall box.
- Supports surface mounting with a TOU frame.
🎯 Ideal For
- Households with their own TV and radio antenna.
- Antenna installations with several outlets along one cable run.
- Replacing or adding loop-through outlets.
- Flush mounting in round Ø60 mm wall boxes.
- Surface mounting with a suitable TOU frame.
🔧 Connection and Operation
Connect the incoming antenna cable to the outlet’s input. Connect the cable continuing to the next outlet to its output.
Connect the TV to the male IEC connector and the FM radio to the female IEC connector on the front. Complete the installation with a suitable cover plate and mounting frame.
The final loop-through outlet in the series must have a 75-ohm termination resistor fitted to its output. The resistor is purchased separately.
