7784 Multiband Distribution amplifier 4 inputs

High output power distribution amplifier (BI/FM, BIII/DAB, UHF1, UHF2) with separate gain adjustments, DC selection and LTE selection


Johansson offers a new range of high output power Multiband distribution amplifiers. 

The RED compliant amplifiers are fully LTE-ready and have a high gain. 
This ensures a perfect signal quality throughout the building. 
The amplifiers are far more efficient than their predecessors. 

  • 4 inputs: BI/FM, BIII/DAB, UHF1, UHF2 
  • split-band amplifiers with interstage attenuators and dynamic range of 20 dB 
  • high gain, high output power 
  • high input power to ensure input overload is virtually impossible 
  • VDC switchable remote power 
  • compact housing 
  • detachable power supply (included) 
  • -30 dB test output 
  • RED compliant
