Professional HDMI To RF Coax TV Modulator
This professional HDMI to RF modulator is designed for adding HDMI video played from computer, blu-ray player or HD security camera to a digital TV channel for viewing on any HDTV set

This RF modulator unit is fully compatible with any HDMI source and will output a digital HD channel with perfect HD quality video up to 1080p.

Ideal and cost effective solution to distribute 720p, 1080i or 1080p HDMI video signal to an unlimited number of HDTV over the existing coax cables, great for large-scale TV distribution system for class rooms, hotels, restaurant, retail stores, hospitals.

A great digital HDTV channel modulator for distributing any live HDMI video source such as digital cable box, DVD player, signage player, etc, and broadcast through using the existing coax cable line.

Each HD modulator unit can accept and combine the RF output from another modulator into 2 TV channels for output. 

More TVs and A/V modulators can be added to the existing setup for various applications such as:

  • home entertainment
  • educational training
  • security surveillance
  • commercial advertisement/digital signage
  • information display
  • emergency messaging announcement
  • private MATV system

Its programmable TV channel selection allows users to assign any desired TV channel frequency for its RF output. Channel selection is controlled by the front panel push button.

HDMI Input + RF Input
This unit is built with 1 HDMI input, 1 RF input with 1 RF coax output. Any HDMI signal from devices such as satellite receivers, digital TV box, computer, HD player or HD surveillance camera can be modulated by this device into a digital HD channel with ATSC channel frequency of user's choice assigned. [Note: most of the HD surveillance cameras use different HD format for output. So additional converter will be needed before feeding into this modulator]

Its RF input allows this modulator to accept and combine RF output from another modulator so users can have multiple of these modulators working together in a streamline setup without using additional RF coax combiners.

Easy Operation
After finishing the cable hookup, Simply use the push buttons on the front panel to bring up the system menu screen and then choose a desired digital TV channel number in aerial ATSC channel frequency range between CH14 and CH69. 

Then users could use the TV remote to tune into the new channel just created to see their HD video or camera screen showing on the TV screen.

Daisy Chain Setup For Producing Multiple HD Channels
This digital HDMI modulator can be used as a standalone unit or cascading with other units together.

Multiple of these digital modulators can be linked together by feeding the modulated RF output from the first unit into the RF input of the 2nd modulator so more private digital TV channels can be created and combined together in one RF output for large-scale HDTV distribution.

Easy HDTV Distribution
Users can use RF coax splitters to distribute the modulated coax feed to multiple TV displays

Users can also add more of these RF modulators for modulating more HD videos into more digital TV channels and combined them in one coax cable run or using the daisy chain hookup for cascading as described earlier for large-scale private TV channel distribution.

Crystal Clear HD Channel Picture Quality
This HD modulator can deliver 1080p full HD quality at its best, giving users the same picture quality as transmitted through HDMI cable.

HDMI Extension Over Coax Cable
This HDMI to RF modulator can also be combined with our digital TV tuner box, model DTV103, so they can be used as a HDMI video/audio over coax cable extender kit for HD content distribution purpose.

Typical uses of this HD type digital RF modulator including:

  • DIY CCTV Surveillance: video from surveillance camera or CCTV DVR can be modulated into new private digital TV channel. So users can simply view the live camera feed on the TV by tuning into the custom TV channel for review or recording. [Note: most of the HD surveillance cameras use different HD format for output. So additional converter will be needed before feeding into this modulator]
  • Education/Training: build private TV channels for broadcasting the computer screen or digital media content prepared by teacher or instructor for classrooms. Any TV connected in the same coax cable can watch the custom-made TV channel created by using this HD RF modulator.
  • Digital Signage: converting digital media content played from DVD player or any digital media player into a commercial TV channel and transmitted over multiple TV displays in public place for advertisement or signage purpose.
  • Retail Store Advertising: retail store owners can use TVs to play their own video ads on TVs through single coax cable run inside the retail store. No internet or network connection needed.

Powerful 100db Output For Long Range Transmission
This RF modulator is featured with a powerful 100dB output, which is sufficient for long cable transmission up to 1200 meters with no loss of picture and sound.

Analog video/audio signals transmitted over existing coax cable with such high dB strength can offers far longer distance than the typical balun or Cat5 extender solution.
