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
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
