Professional RF Coax To Composite Video Audio Demodulator TV Tuner
For NTSC System
This RF to composite A/V demodulator is a professional grade TV channel converter, designed to work with coax TV signals such as cable
TV or satellite channels, closed circuit TV channels or other RF modulated signals by converting such
RF coax feeds into
standard RCA formats for various applications such as displaying,
recording, or further A/V broadcast and distribution.
This coax cable signal converter provides convenient decoding solution for extracting the video/audio embedded in the
RF signals coming from cable outlets or cable boxes, satellite
set top boxes or CCTV camera/DVR systems.
Its availability offers cost-efficient solution and helps for those coax setups found in public A/V broadcast, MATV, SMATV systems used in campus, classrooms, hotels,
condos, hospitals, sports bars, restaurants or individual residence.
This device supports all the coax type A/V signal inputs from:
- TV/RF out port of the cable box or cable outlet for analog TV
- UHF/VHF channel broadcast or
- Satellite receivers or other set top boxes
with TV/RF out ports
- Modulated CCTV surveillance system
- Cable radio or cable FM station
- RF modulators used in MATV setup

Full-Frequency UHF VHF CATV Channel Decoding
This RF coax demodulator doubles as an external TV tuner for analog TV signals.
It has a full-frequency analog TV tuner and able to decode all standard
UHF/VHF TV, CATV channels from cable outlets, aerial antenna, set top boxes or
TV tuner unit can also decode those RF/TV out from satellite receivers and
free-to-air set top boxes into separate RCA video audio feeds.
Easy Add-On TV Tuner Module
This coax demodulator can be an external TV tuner module for video monitors, projectors, DVR systems or all other video equipments
that do not have RF coax inputs.
Great add-on item for expanding their A/V equipments with a new RF/coax input.
Great TV Channel Audio Extractor

always be added back if needed. IR remote is sold
Video Audio Extension Over Coax Cable
Coaxial cables offer a low-cost solution for long distance signal
transmission line than the typical balun or Cat5 extender.
This RF demodulator can also be combined with our RF modulator so they can be used as a video/audio over coax cable extender kit for many purposes such as CCTV surveillance, multimedia center, etc.
Auto Gain Control
This coax converter is featured with AGC circuitry for auto adjustment on both video and audio levels. The output quality will be re-calibrated and retained the picture stability as the original input A/V signal for the remote end display with minimum distortion and noise-free with full brightness and contrast.
Last Channel Memory
This coax demodulator tuner unit will stay tuned to the same last TV channel when the power comes back up after power outage.
