The Anttron TRM84 is a digital compact headend that transmodulates free-to-air (FTA) satellite programs from up to 8 DVB-S/S2 transponders across 4 SAT inputs into 4 adjacent DVB-T or DVB-C output channels. The integrated remultiplexer allows programs from any of the 8 transponders to be freely assigned to any of the 4 output MUX, giving installers precise control over which channels appear at each distribution point.

The TRM84 is designed for cost-effective satellite channel distribution in existing coaxial networks — hotels, hospitals, nursing homes, and similar multi-room installations. It supports LCN (Logical Channel Numbering) and remote administration via web interface over Ethernet or LAN.

Key Features

• 4 SAT inputs covering 8 DVB-S/S2 transponders
• 4 adjacent DVB-T or DVB-C output channels (MUX)
• Integrated remultiplexer for free assignment of satellite programs to output MUX
• LCN (Logical Channel Numbering) support
• USB input for programming via PC
• RJ45 port for LAN programming and remote web-based administration
• Adjacent-channel-capable modulators

Product Benefits

• Converts satellite channels for distribution over existing coaxial infrastructure — no new cabling required
• Remultiplexer lets the operator select exactly which satellite programs reach each output MUX
• Web-based remote management reduces the need for on-site visits after initial setup
• Four adjacent output channels maximise the number of programs distributed within a tight frequency plan
• LCN support ensures TV sets display channels in the correct numbered order without manual retuning
