Johansson 7784 - Multiband Amplifier 4 Inputs

Johansson 7784

Multiband Amplifier with 4 Inputs and LTE filter

 Johansson 7784 is a high output power distribution amplifier (BI/FM, BIII/DAB, UHF1, UHF2) with separate gain adjustments, DC selection and LTE selection. The  RED compliant amplifier is fully LTE-ready  and have a high gain. This ensures a perfect signal quality throughout the building. This amplifier is far more efficient than its predecessor.

Feautures of multiband amplifier

• 4 inputs: BI/FM, BIII/DAB, UHF1, UHF2
• split-band amplifier 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
