Wireless HDMI Extender ATEN KHExt50 5.8 GHz, up to 50 m range

ATEN KHExt50 is a wireless HDMI extender operating in the 5.8 GHz band that transmits uncompressed HDMI video and audio up to 50 meters without a cable connection. The kit includes a transmitter and a receiver for a point-to-point wireless HDMI link, maintaining HDMI connectivity while removing the need for long cable runs. This solution is intended for environments such as meeting rooms, digital signage and AV installations where routing or concealing HDMI cables is impractical.

Advantages

The ATEN KHExt50 provides a stable wireless HDMI connection over the 5.8 GHz frequency, delivering full HDMI audio and video signals across a range of up to 50 m in line-of-sight conditions. By including both transmitter and receiver units it simplifies setup and avoids complex cabling. The solution preserves HDMI signal quality for typical presentation and signage uses and reduces installation time and physical infrastructure requirements.

Suitable for

• Conference and meeting rooms where sources must be connected to displays without long HDMI cables
• Digital signage installations in retail, hospitality or public spaces
• Temporary AV setups for events, presentations and trade shows
• Small AV installations where wall or ceiling cable routing is difficult or undesirable

Key specifications

• Wireless frequency: 5.8 GHz band
• Maximum wireless range: up to 50 meters (line of sight)
• Connectivity: HDMI video and audio transmission
• Kit composition: one transmitter unit and one receiver unit for point-to-point link
• Signal type: preserves HDMI digital audio and video format

How to use

Place the transmitter near the HDMI source and the receiver near the display, ensuring clear line of sight where possible to maximize range and signal stability. Connect the HDMI output of the source to the transmitter and the HDMI input of the display to the receiver. Power both units according to the supplied power adapters. After powering on, allow the units to pair; the wireless link is established for point-to-point HDMI transmission. Adjust placement if interference or reduced range is observed.

Usage recommendations

For best performance, install the transmitter and receiver with minimal obstructions between them and avoid dense Wi‑Fi or other 5.8 GHz RF traffic in immediate proximity. Use line-of-sight placement when possible and keep the units away from large metal structures or sources of strong electromagnetic interference. For permanent installations, verify signal stability at intended mounting positions before finalizing installation.
