## Summary description

The Kathrein EXE 2581 is a high-performance satellite multiswitch with 5 inputs and 8 outputs. It operates within a frequency range of 950 - 2150 MHz and supports input voltages from 60 to 90 dBμV, delivering an output voltage of 92 dBμV. With a current consumption of 240 mA, its compact dimensions (160 mm width, 148 mm depth, 43 mm height) make it ideal for various installations, ensuring reliable signal distribution for multiple satellite receivers.

## Long description

The Kathrein EXE 2581 is a compact satellite multiswitch with five inputs and eight outputs designed for distributing satellite signals to multiple receivers. It supports single-cable (Unicable) distribution and complies with the extended single-cable standard, offering cascade capability and automatic gain control (AGC) for stable signal levels across connected devices.
Advantages
The multiswitch covers a frequency range of 950–2150 MHz and provides an output level of 92 dBµV with input sensitivity between 60 and 90 dBµV. It features F-type connectors, low current consumption (240 mA), and a compact housing (160 × 148 × 43 mm), making it suitable for installations with limited space. Cascade capability allows system expansion while the AGC function helps maintain consistent signal quality.
Suitable for
 Distribution of satellite signals to up to 8 receivers
 Single-cable (Einkabel/Unicable) multi-receiver installations
 Apartment buildings or homes requiring cascade expansion
 Installations using F-type coaxial connections

How to use
Connect the satellite dish LNB outputs to the five inputs of the EXE 2581 using F-type coaxial cables. For single-cable (Einkabel/Unicable) installations, configure the multiswitch according to the receiver and LNB addressing scheme so that one output can serve up to eight receivers. Use cascade ports if you need to expand the system further. Ensure power is supplied as specified and verify signal levels at each receiver to confirm proper distribution.
Usage recommendations
Install the multiswitch in a dry, ventilated location and use quality F-type coaxial cables to minimize signal loss. When expanding via cascading, check signal levels and shielded cable routing to avoid interference. Follow receiver and LNB documentation for correct Unicable addressing.
