WISI FLEXSWITCH Line Amplifier DXA0505 4xSAT/1xTERR for Multiswitch Cascades

In large satellite distribution systems, signal loss across long cable runs and cascaded multiswitches can degrade picture quality and limit the number of connected receivers. The WISI FLEXSWITCH DXA0505 line amplifier solves this by boosting both satellite and terrestrial signals, ensuring stable levels throughout the cascade.

Who is it for

Professional installers and system integrators deploying multiswitch cascades in MDUs, hotels, or larger residential complexes where signal attenuation is a concern.

Main features

• Amplifies 4 satellite IF polarities and 1 terrestrial band simultaneously

• Operating temperature: -20 to +50 °C

Tips

For optimal performance, install the amplifier at a point where signal levels are still sufficient to ensure a good signal-to-noise ratio. Use the adjustable attenuators to balance levels between SAT and TERR paths.
