DC & IR Passing 4-way Splitter / Combiner

The Model 2514 DC & IR Passing 4-way Splitter/Combiner is a bi-directional 4-way splitter / combiner that provides a 1 GHz bandwidth and is ideal for antenna and coaxial cable operations. The splitter/combiner can be used for two applications. It can be used to split a signal from a source or combine signals from multiple sources onto one coax run. Use a DC passing splitter whenever DC IR signals are present on the coax. Also available in a 25 pack as Model 2514-25.


  • 1 GHz bandwidth
  • 8 dB insertion loss
  • Passes DC IR signals on the coax
  • Use as signal splitter or combiner
{tab FAQs}
Any recommendations when using this splitter with IR-Over-Coax product?
Yes, we recommend using DC blockers in IR systems. The trick with IR is voltages. A standard splitter uses diodes, meaning voltage only flows in one direction. These splitters allow voltages to flow in both directions. Having products like unearthed TVs in the system can cause issues. It's recommended that DC blockers (RLACC130) are used at the TV sockets to avoid voltages leaking back into the system. This should ensure reliable IRperformance.
