Splitter In Practice
An RF splitter divides one feed among several outputs while keeping impedance matched and isolation between the ports. The loss is unavoidable and predictable, so the design question is always whether the system budget can carry the split you want.
Problems This Range Solves
- Signal levels that fall below usable after an unplanned split
- Poor port isolation allowing interference between branches
- Impedance mismatch introduced at the splitting point
- Outdoor splitters that corrode and drift out of specification
- Split ratios chosen without a level calculation
Who It Is For
- Distributed antenna system integrators
- Broadcast and CATV distribution engineers
- Wireless network installation contractors
- CCTV and security system installers
- Building services teams distributing RF
Where It Is Used
- Feeding several antennas from one source in a DAS
- Distributing a broadcast feed to multiple outputs
- CCTV signal distribution to several recorders or monitors
- Splitting a test signal across multiple instruments
- Branching a feeder run inside a building

Where This Range Is Specified
Specifying and Handling Splitter
Before You Order
- Calculate the level at every output before committing to a split ratio
- Terminate unused ports with the correct load rather than leaving them open
- Keep impedance consistent through the whole distribution chain
On Site
- Mount in a sheltered position unless the housing is rated otherwise
- Sweep the system after installation to confirm return loss
- Record the split plan so future additions can be budgeted
Splitter Questions
How much loss does a splitter add?
At minimum the theoretical division loss, plus the insertion loss of the device. Two way and three way splits differ, so calculate the level at each output before you commit the design.
What happens if I leave an output unterminated?
You get a reflection from the open port that degrades the whole system. Unused outputs should be terminated with a correctly rated load.
Which connector interfaces are available?
Standard RF interfaces matched to the feeder and connector range from the same catalog. Tell us your system's interface and we will confirm the version.
Are outdoor rated versions available?
Standard housings suit indoor and sheltered installation. If the splitter will be exposed, tell us and we will confirm what is suitable rather than leaving it to fail in service.
Can splitters be cascaded?
Yes, but the losses add. Two cascaded two-way splits are not the same as one four-way in level terms, so work the budget through the whole tree.
