Televes 4131 kulma-IEC-TV-rasia FM- ja SAT-lähdöillä

In hotels and apartment blocks with MATV/SMATV systems, routing thick coaxial cables behind wall-mounted TVs without bending them sharply is a common challenge. The Televes 4131 terminal socket solves this by combining terrestrial TV, FM radio, and satellite connections in one flush-mounted unit. Its angled IEC male connector reduces cable strain, while the IEC female and F-type female outputs feed radio tuners and satellite receivers. Built on a robust Zamak chassis with Class A shielding, it delivers clean signals across all three services.

Why choose it

The angled IEC connector prevents sharp bends in coaxial cables, ensuring reliable signal integrity and easier installation in tight spaces. Its robust Zamak chassis and Class A shielding protect against electromagnetic interference, delivering clean signals for all three services. The integrated DC pass allows remote powering of satellite LNBs without extra hardware.

Ideal use cases

• Residential apartments with combined terrestrial and satellite TV
• Hotel rooms requiring multiple signal outlets
• MATV/SMATV distribution systems in commercial buildings

Good to know

This socket is designed for flush mounting in standard wall boxes. The Zamak chassis provides durability and effective shielding, while the plastic cover offers a clean finish. The angled TV connector is particularly useful when the TV is mounted close to the wall, minimizing cable stress and potential signal loss.
