Satellite Multiswitch Kathrein EXR 2558 Grey

The Kathrein EXR 2558 Grey is a compact, indoor satellite multiswitch designed to distribute four satellite polarisation/band levels and terrestrial signals to multiple receivers. It supports a frequency range from 47 to 862 MHz, uses F-type RF connectors and provides one terrestrial input, four satellite outputs and eight subscriber (sub) outputs. The unit includes an integrated amplifier and pre-emphasis circuitry to compensate cable attenuation and keeps terrestrial reception available even when satellite receivers are switched off. The device draws about 20 mA and measures 159 x 148 x 43 mm, weighing 0.45 kg. It requires an AC power supply in the range 198–253 V.

Advantages

The multiswitch allows independent selection of horizontal/vertical and low/high bands per receiver while needing only one downlink cable per single receiver (two for twin receivers). It is cascade-capable for system extension, provides a high degree of insulation between outputs to reduce crosstalk, and accepts remote feeding via the horizontal low inputs while other inputs remain voltage-free for compatibility with UAS 485/585 devices. An integral amplifier and pre-emphasis reduce attenuation-related signal loss over long coaxial runs, and terrestrial signals remain available in passive band 5–862 MHz.

Suitable for

• Small to medium shared satellite installations in homes or apartments
• Distributing satellite and terrestrial TV signals to multiple single or twin receivers
• Systems requiring cascade expansion or remote power feeding

How to use

Install the multiswitch indoors and connect the dish LNB outputs and terrestrial antenna to the appropriate inputs using F-type coaxial connectors. Connect receivers to the sub outputs; each single receiver requires one downlink cable while twin receivers require two. If required, cascade additional multiswitches by linking appropriate inputs/outputs according to system design. Provide AC mains power (198–253 V) to the unit; remote feeding of the device is possible via the horizontal low inputs while keeping other inputs voltage-free for compatibility with UAS 485/585 equipment.

Usage recommendations

To maintain signal quality over long coax runs, use good quality RG-6 or equivalent coaxial cable and follow the device’s pre-emphasis and amplifier settings. Ensure correct polarity and secure F-type connections; for larger installations, plan cascade stages and power feeding to avoid overloading any single feed point.
