8K HDMI 2.1 Extender over HDBaseT

The Gefen GF-EXT-HD-HBT extends HDMI 2.1 signals up to 150 metres over a single CAT cable. It delivers visually lossless 8K at 30 Hz or 4K at 120 Hz with HDR10+, Dolby Vision and HLG support. HDCP 2.3 compliance protects premium content. The kit includes transmitter and receiver units, a locking 12 V power supply, Phoenix connectors and mounting ears for professional AV installations.

Verify cable category and HDMI version

Confirm the CAT cable rating meets the bandwidth required for the target resolution and distance. The source must output HDMI 2.1 and the display must accept the intended resolution and refresh rate. Ensure the locking 12 V power supply can reach an outlet at both the transmitter and receiver locations. Check that the Phoenix connectors match the control system wiring plan.

Integrates with control systems and USB

Two RJ-45 ports provide network connectivity for IP-based control alongside the HDBaseT link. Dual USB ports allow peripheral extension such as keyboards, mice or touchscreens. Two IR inputs enable remote source control from the display side. The compact 10.4 by 8.1 by 3 inch chassis fits standard racks using the included mounting ears, freeing the source equipment from the display location.

Questions about this item

Does the box include both the transmitter and receiver, or do I need to buy a second unit separately?

The package contains one transmitter unit, one receiver unit, a locking 12 V power supply, Phoenix connectors, mounting ears and a quick start guide.

Should I choose the 8K60 Hz or the 4K120 Hz capability for my installation?

The extender handles both; it delivers 8K60 Hz 4:2:0 and 4K120 Hz up to 90 m, 4K60 Hz 4:4:4 up to 120 m, and 1080p60 up to 150 m over a single CAT cable.

What does the 40000 MHz bandwidth mean when the extender is connected to an 8K display?

That bandwidth supports visually lossless 8K60 Hz 4:2:0 or 4K120 Hz signals with HDR10+, Dolby Vision and HLG, all protected by HDCP 2.3.
