Extend HDMI over CAT5/CAT6 cabling to a remote location, with support for 4K 60Hz at 70 m (230 ft.) and 1080p 60Hz at 100 m (328 ft.)

This HDMI Over CAT6 extender transmits your HDMI audio/video signal to a remote location up to 100 m (328 ft.) away.

Get 4K at 60Hz from 70 m (230 ft.) away

This HDMI over CAT6 extender maintains your Ultra HD 4K picture quality, even at 70 m (230 ft.) away from your video source. If you're not running 4K video, this extender supports High-Definition 1080p 60Hz and lower resolutions at even greater distances, up to 100 m (328 ft.) from your HDMI source.

With full support for your HDMI 2.0 equipment, including 4K resolution at 60Hz, this extender can transmit at a bandwidth of up to 18Gbps, making it the ideal solution for high-resolution tasks requiring the highest color detail. For smoother video and color transitions, the extender offers 4:4:4 chroma subsampling via visually lossless compression, meaning every pixel gets its own unique color.

Simplify your setup

The HDMI Extender Over CAT6 offers a hassle-free solution for your digital signage project. The extender only requires a single CAT5e or CAT6 cable, so you extend an HDMI signal using existing infrastructure that’s already in your building. Plus, this HDMI extender supports Power Over Cable (POC), which means you’ll only need one power adapter connected to either your transmitter or receiver. Mounting hardware is also included for discreet, professional installation.

The ST121HDBT20L is TAA compliant and backed by a 2-year warranty with free lifetime technical support.
