KATHREIN ESU 51 Antenna Outlet – 3 Sockets (SAT, TV, Radio), Flush-Mount, F/IEC Connectors 21110061

The KATHREIN ESU 51 stands out with its triple-output design, combining satellite, television, and radio connectivity in a single flush-mount wall outlet. This integration eliminates the need for multiple separate sockets, making it a practical choice for structured cabling in residential and commercial installations.

Highlights

• Three dedicated outputs: SAT (F-type male), TV (IEC female), Radio (IEC male)
• Wide frequency coverage: 5–862 MHz for TV/Radio, 950–2200 MHz for satellite
• Low insertion loss of 1.5 dB across all outputs
• DC pass-through for satellite (max 500 mA) to power LNBs or multiswitches
• High shielding factor > 75 dB for interference-free signal transmission

In daily use

Install the ESU 51 in a standard flush-mount box and connect your coaxial cables to the clearly marked terminals. The satellite output passes DC power, enabling remote powering of an LNB without extra hardware. Its robust shielding ensures stable TV and radio reception even in environments with high electromagnetic noise.
