The Johansson Transmodulator 5310Q ProTerr ETH is a digital terrestrial transmodulator that takes DVB-T/T2 input channels and re-maps them to different terrestrial frequencies for distribution via coaxial cable to connected televisions. It handles up to 32 channels and allows each output frequency to be assigned independently, so operators can decide exactly which channels each television receives.

Configuration and monitoring are handled remotely over LAN, using a modern graphical user interface. This allows installers and operators to manage the system without being physically present at the rack.

Key Features

• Distributes up to 32 digital terrestrial channels over a single coaxial cable infrastructure
• Output frequencies are individually reconfigurable to any terrestrial digital frequency in range
• Frequency range: 47 – 862 MHz, covering VHF and UHF bands
• Channel bandwidth: 7 MHz (VHF) / 8 MHz (UHF)
• Modulation: QPSK, 16-QAM, 64-QAM
• Output level: 68 to 83 dB, continuously adjustable
• Capacity: up to 8 channels per unit
• 10 connections per unit
• LAN management interface with modern GUI for remote configuration

Product Benefits

• Remote LAN management means system changes — frequency reassignment, level adjustment — can be made without visiting the headend
• Adjustable output level (68–83 dB) lets the installer match the signal level to the distribution network length and splitter losses
• Wide modulation support (QPSK, 16-QAM, 64-QAM) accommodates different channel encoding schemes from the input source
• Coaxial distribution keeps the existing cable infrastructure in use — no rewiring required
