The Anttron TM300 is a dual-input RCA to DVB-T modulator. It accepts two composite video sources via 3RCA Cinch and two F female (MIX) connectors, then encodes and modulates them as a DVB-T COFDM signal across the UHF frequency range of 470–862 MHz. This makes it suitable for distributing sources such as set-top boxes, DVD players, or gaming consoles to multiple televisions in hotels, hospitals, or other centralised antenna systems.

The output channel bandwidth is selectable at 7 or 8 MHz, with adjustable output level and a choice of QPSK, 16QAM, or 64QAM modulation, allowing integration into existing DVB-T distribution networks.
