This HDMI over CAT6 extender with 3-port HDMI switch features HDBaseT™ and is TAA Compliant. Astonishing 4K over CAT6 This HDMI Extender with a built-in Switch is capable of extending 7.1 audio and 4K at 30Hz video up to 115ft (35m), or 1080p up to 230ft (70m). The transmitter and receiver kit is connected using a single CAT5e/6 cable to avoid the hassle of running multiple cables.
