Kathrein ESM 30 Triple Antenna Outlet Socket for TV, Radio, and Satellite (Star Network)

Distributing satellite, terrestrial TV, and radio signals to a single wall outlet without signal loss or interference is a common challenge in modern home entertainment and connectivity setups. The Kathrein ESM 30 antenna outlet socket solves this by providing a single, flush-mounted connection point that supports all three services simultaneously, ideal for star network installations.

Who is it for

This socket is designed for professional installers and homeowners who need a reliable, high-performance triple outlet for connecting satellite receivers, TVs, and radios from a central distribution system. It is particularly suited for star topology networks where each outlet is fed individually.

Main features

• Triple configuration: one satellite (F-type female), one TV (IEC male), and one radio (IEC female) output.
• Wide frequency range: 5–862 MHz for TV/radio and 950–2200 MHz for satellite.
• Low through loss of 4 dB for both TV/radio and satellite paths.
• DC pass for satellite (max 24V / 0.5A) to power LNBs or switches.
• High shielding effectiveness (Class A) and return loss >10 dB for clean signal.
• Robust die-cast zinc housing for durability and long service life.
• Flush-mounted (Unterputz) design for a neat, professional finish.
