Antiference Conexer Quad HD DVB-T Modulator

Quad Input HDMI to DVB-T/C Digital Encoder Modulator

This state-of-the-art digital encoder provides a professional solution for distributing high-definition content across existing coaxial networks. By taking video and audio signals from four separate HDMI sources, this unit converts them into a single digital terrestrial (DVB-T) or cable (DVB-C) multiplex.

We designed this high-density modulator to simplify the delivery of multiple HD channels—such as satellite receivers, media players, or digital signage—to an unlimited number of televisions. The unit features a selectable RF output, allowing you to configure the broadcast to match your specific infrastructure requirements while maintaining full control over channel identity and placement.
