The 4K HDMI extender uses HDBaseT to transmit your HDMI A/V signal to a remote location up to 70m (230ft) away. The transmitter in this HDMI HDBaseT extender kit features a small footprint and built-in HDMI cable that connects directly to your source for reduced clutter. It’s powered from a USB port on your source device, which makes it easier to install in areas where power outlets may be limited. Mounting hardware is included for the receiver for a discreet, professional installation. This HDMI over CAT6 extender maintains your UHD 4K picture quality, even at 130ft away from your video source. Because the extender is backward compatible with 1080p and lower resolutions at 230 feet away, you can comfortably use this extender to make any video source look great. The extender also supports 7.1 audio to ensure all audio channels are captured.
