Connect the Transmitter Unit to an HDMI source and the Receiver Unit to an HDMI display to wirelessly transmit 4K 60Hz HDMI at distance of up to 165 feet (50 meters), using this Wireless HDMI Extender Kit.

No Line-Of-Sight Required

This wireless HDMI extender eliminates the need for a separate ethernet cable between the transmitter and receiver, providing a clean and flexible setup. Operates with or without line of sight (LOS/NLOS), making it ideal for media closets and cabinets. Also, the transmitter features an HDMI output for connecting a local display, making it ideal for presentations and conferences. A 5GHz point-to-point connection between the transmitter and receiver avoids the more congested 2.4GHz wireless frequencies. Up to four paired extender kits can be used in the same area.

No Drivers or Software

This wireless HDMI extender offers a straightforward, plug-and-play experience, eliminating the need for IP configurations, software installations, or driver setups, making it an accessible solution for various applications.

Versatile Installation Options

The included mounting kits enable versatile installation options for both the transmitter and receiver. An IR blaster and receiver are also included to extend infrared signals. Optional rubber feet are included for added stability and surface protection.

High-Performance Wireless Extender

This extender supports HDMI 2.1 TMDS with 18Gbps bandwidth, HDCP 1.4/2.2, 2.1 channel audio, and Audio Return Channel (ARC). It uses a dual-antenna design for improved wireless performance. This wireless HDMI extender features 8kV air and 6kV contact electrostatic discharge (ESD) protection.
