HDMI Extender over Cat5e/6/7

This HDMI extender sends 4K video and audio up to 394 feet over a single Cat5e, Cat6 or Cat7 cable. The transmitter and receiver set requires no drivers and installs in seconds. It is aimed at installers and home users who need long-distance HDMI runs without the cost of long HDMI cables.

Best for fixed installs up to 4K@30 Hz

Suits setups where the source and display are far apart — such as digital signage, conference rooms or whole-home AV — and where 4K at 30 Hz meets the requirement. Not suited for users who need higher refresh rates at 4K or who want to run the signal over fibre or wireless links.

Maximum 4K@30 Hz over 394 ft

The extender accepts HDMI input up to 4K at 30 Hz and delivers it over 120 metres of pure copper Ethernet cable with zero added latency. This resolution and distance limit is the single spec that decides whether the kit fits the project.

Questions about this item

How do I connect the transmitter and receiver units with the Cat6 cable for the 394ft run?

Connect the HDMI source to the transmitter, run a single pure-copper Cat5e/6/7 cable up to 120 meters to the receiver, then attach the display to the receiver; the loop-out port on the transmitter mirrors the signal locally.

What ongoing upkeep does the extender need after installation?

No firmware or driver updates are required; only inspect the RJ45 connectors and Ethernet cable for physical damage or corrosion if the link drops.

At what resolution and refresh rate does the 4K signal remain stable over the full distance?

The extender supports up to 4K at 30 Hz across the full 120-meter link; higher refresh rates are not supported.
