Distribute a compatible mobile signal booster’s output to three indoor antennas with a 3-way N splitter. This passive divider provides three separate cable branches, making it easier to plan antenna placement across multiple rooms, corridors or floors.
The splitter operates from 800–5000 MHz and can be used with compatible 4G, 5G and other RF systems within that range. This includes frequencies around 800, 900, 1800, 2100, 2600 and 3500 MHz. Check that every operating band in the installation falls within the specified range.
With one input and three outputs, all N female, the splitter connects using antenna cables with N male connectors. It has 50 Ω impedance and a stated maximum power rating of 200 W.
Its cavity construction features a black aluminium housing and silver-plated phosphor bronze inner conductors. Dimensions of 210 × 60 × 25 mm make it practical for fixed installation along the antenna cable route.
The splitter distributes available signal power; it does not amplify it. Allow for both splitting loss and cable attenuation in each antenna branch. Appropriate planning helps create a balanced antenna distribution system.
✅ Benefits
- Three antenna outputs – distribute one common connection across three cable branches.
- 800–5000 MHz – covers several mobile bands, including 5G around 3.5 GHz.
- N female connectors on all ports – connect matching N male cables.
- 50 Ω impedance – for compatible signal booster and RF systems.
- Stated 200 W power rating – subject to the installation’s operating conditions.
- Passive design – no separate power supply required.
- Aluminium housing and silver-plated inner conductors – construction for fixed antenna installations.
🎯 Ideal for
- Mobile signal boosters serving three indoor antennas.
- Signal distribution across several rooms or floors.
- Compatible 4G and 5G installations within 800–5000 MHz.
- 50 Ω antenna systems with N connectors.
🔧 Connection and use
Connect the compatible booster’s cable to the splitter’s common input. Connect the three antenna feeds to the outputs. Use 50 Ω coaxial cables with N male connectors and follow the product’s port markings.
Plan each branch according to cable length, attenuation and antenna position. Support the cables so their weight does not strain the connectors.
Check frequency and power compatibility throughout the system. Handle unused ports according to the manufacturer’s instructions.
A splitter does not create MIMO. Separate MIMO signal paths must remain separate according to the equipment’s installation instructions.

📉 Splitting loss
An ideal equal three-way split introduces approximately 4.77 dB loss per output, before additional component and cable losses.
The supplied insertion-loss figure of ≤ 0.1 dB requires confirmation as excess loss above theoretical splitting loss. It is not presented here as total loss per output.
