Multiconmutador Kathrein EXR 158 gris

The Kathrein EXR 158 Grey multiswitch distributes satellite and terrestrial signals to multiple subscribers. It accepts four satellite inputs and one terrestrial input, covering a frequency range of 47–862 MHz. The device includes F-type RF connectors and an integrated 18 V/550 mA power supply for satellite line powering, supporting signal distribution to up to eight subscriber outputs. Compact and lightweight, it is intended for structured distribution in residential or small commercial satellite reception systems.

Advantages

The multiswitch provides simultaneous distribution of satellite and terrestrial signals to eight outputs with low connection loss across specified bands. Built-in power supply reduces the need for an external PSU, and standard F-connectors ensure compatibility with common coaxial cabling. Its frequency range of 47–862 MHz supports both satellite IF and terrestrial broadcasting services.

How to use

Connect the four satellite LNB feeds to the satellite inputs and the terrestrial antenna to the terrestrial input using F-type coaxial connectors. Attach each subscriber cable to the eight output ports. Ensure the integrated power supply is connected to mains (198–253 V AC) so the multiswitch can supply 18 V/550 mA to the satellite lines. Verify polarity and secure connections to minimize signal loss.

Recommendations

Install the multiswitch in a dry, ventilated location close to the incoming antenna cabling. Use quality coaxial cables and properly tightened F-connectors. If signal levels are weak, check LNB alignment and cable integrity before adding amplifiers; observe the specified connection loss values when planning distribution.
