The VeCOAX MINIMOD 2+ is a professional CATV modulator that injects any HDMI source into your cable-TV (CATV) lineup as a clean, tunable channel over the building's coaxial cable. CATV systems carry many channels on one coax, and this modulator adds yours to the mix: feed in a cable box, Apple TV, camera, signage player or laptop, pick a free channel on the front-panel color LCD, and every TV on the CATV plant tunes it in full 1080p with Dolby Digital audio - no streaming apps, no computer.Adding a channel to a live CATV system demands a modulator clean and strong enough to coexist with the existing lineup. The MINIMOD 2+ uses a Full Digital DDS synthesizer for spurious-free output that won't disturb neighboring CATV channels, drives a powerful +45 dBmV for runs up to roughly 9,800 ft across splitters and amplifiers, and holds MER above 45 dB so your channel looks flawless on every set in the system.It outputs the CATV-standard QAM plus ATSC, DVB-T, DVB-C and ISDB-T - selectable on the LCD in under a minute, no PC required. Designed and built in the USA, backed by a 5-year manufacturer warranty and free unlimited lifetime tech support.
