KATHREIN EXR 2554 multiswitch δορυφορικού/επίγειου σήματος

The KATHREIN EXR 2554 is a passive multiswitch that distributes satellite and terrestrial signals to up to four receivers without external power. It combines four satellite polarizations and one terrestrial input, supporting DiSEqC 2.0 control and a return path for interactive services.

Overview

Designed for small distribution systems, the EXR 2554 routes signals from one satellite (four polarizations) and terrestrial sources to four subscriber outputs. Its passive design requires no power supply, relying on receiver-provided LNB power.

What stands out

• Passive operation – no external power needed
• Four subscriber outputs for multi-room setups
• Supports DiSEqC 2.0 control protocol
• Built-in terrestrial return path (5–65 MHz)
• Class A shielding for signal integrity

Technical details

• Satellite inputs: 4 (1 satellite, 4 polarizations)
• Terrestrial input: 1
• Subscriber outputs: 4
• Satellite frequency range: 950–2200 MHz
• Terrestrial frequency range: 5–862 MHz
• Through loss: 2.5–4 dB (satellite and terrestrial)
• Isolation SAT-SAT: >30 dB
• Connectors: F-type
• Operating temperature: -20 to +50 °C

Our verdict

A reliable passive multiswitch for distributing satellite and terrestrial signals to four outlets, ideal for small residential installations.
