Maximize Your Coverage and Minimize Interference

 Introducing the Complete PRO-MCU380-EXT Series for Extended TETRA Band Communication

When communication matters most, you need full coverage and zero interference.
The PRO-MCU380-EXT series delivers high isolation, compact design, and reliability across extended TETRA bands.

 

The TETRA Combiner Advantage

 

image001

 

The difference is clear.
Using a mobile TETRA combiner dramatically improves isolation between radios:

  • With a combiner: Typical isolation exceeds 60 dB, ensuring interference-free signals.

  • Without a combiner: Isolation drops to 10–15 dB, leading to degraded performance and possible communication loss.

This visual highlights why the PRO-MCU380-EXT series is essential for vehicles or control centers running multiple TETRA radios in parallel.

 

Why It Matters

  • Radios installed in the same vehicle often have only 10–15 dB isolation, causing interference and degraded audio.

  • The PRO-MCU380-EXT series boosts isolation to > 60 dB, delivering clear, stable communication under all conditions.

  • Each model supports 25 W max input power and is ETSI compliant, vibration/shock tested (EN-60068), and optimized for mission-critical networks.

  

Key Features

  • Optimized for extended TETRA band (380–386.5 / 390–396.5 MHz)

  • Isolation > 60 dB between all ports

  • Compact for mobile and fixed use

  • ETSI compliant & EN-60068 tested

  • Max 25 W input power per port
