All-Channel NTSC Composite BNC/RCA Video Audio To RF Coax TV Modulator
This RF/coax agile modulator converts standard composite video/audio from such as satellite receivers, Digital TV converter box, DVD player or CCTV surveillance camera to a user-defined cable or UHF/VHF V channel output. Any TV connected to the output from this RF modulator via coax cable connection can receive the same A/V signal when tuned to the specific channel.
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.
Air/CATV Video System Support
This video/audio modulator is ideal for encoding audio/video onto any unused TV channel. One model with selectable system mode and wide channel frequency range support for both air UHF/VHF and CATV channel output.
Long Range Transmission
Featured with a powerful 100dB output, which is sufficient for long cable transmission up to 1200 meters with no loss of picture and sound.
Easy Expansion
Users can add more of these RF modulators for more video sources to be transmitted simultaneously through using RF combiner over the same coax cable wire.
Video Audio Extension Over Coax Cable
This RF modulator can also be combined with our RF demodulator, RFDM2 model, as a video/audio over coax cable extender kit.
Adjustable Video Audio Level Control
Featured with adjustable level controls of the video/audio input feed so the picture stability will be retained all the way with full brightness and contrast.
1U 2U 3U Rack Mountable Design
The optional rack-mount kits are available in 1U, 2U or 3U style and sold separately.
