The VeCOAX MINIMOD 2+ is a professional HDMI RF modulator that converts any HDMI source into a clean, broadcast-grade RF television channel and carries it across your existing coaxial cable to unlimited TVs. An RF modulator takes baseband video and audio and places it on a specific radio-frequency channel; this one accepts HDMI from a cable box, Apple TV, Roku, camera, signage player or laptop, encodes it in full 1080p with Dolby Digital audio, and outputs a real digital channel that every coax-connected TV can tune like any other station - no streaming apps, no set-top boxes, no computer.Unlike low-cost RF modulators that pixelate over long runs or interfere with adjacent channels, the MINIMOD 2+ is built to broadcast specifications. It delivers a powerful +45 dBmV RF output for cable runs up to roughly 9,800 ft, holds MER above 45 dB for an artifact-free picture at the far end, and uses a Full Digital DDS synthesizer so its channel stacks cleanly beside your existing lineup with zero spurious output. Setup takes under a minute on the built-in color LCD - there is no PC or app required.This single RF modulator covers every worldwide broadcast standard - QAM, ATSC, DVB-T, DVB-C and ISDB-T - selectable right on the front panel, so the modulated channel matches whatever your TVs already use. Designed and built in the USA, backed by a 5-year manufacturer warranty and free unlimited lifetime tech support.
