4K HDMI Over Coax Extender Upto 330 Feet - Low Latency 4K@60Hz

In this review the focus is on a single-purpose extender that converts HDMI over existing coaxial runs, and it is best suited for installations where running new HDMI cable is impractical. The bottom line is simple: it reliably delivers 4K@60Hz over long distances with minimal setup, making it a practical choice for AV installs, digital signage, and multi-room distribution. Setup was straightforward, and users will appreciate the low latency and clear video quality without needing to change HDMI or EDID switches in most cases.

Key Features

• 330 ft 4K transmission: Extends HDMI signals over coaxial cable up to 330 ft while supporting up to 4K@60Hz for high-resolution displays.
• HDMI 2.0 and HDCP 2.2 compliant: Ensures compatibility with modern sources and content protection standards for predictable playback.
• Low latency performance: Keeps lag minimal which is important for video conferencing, streaming and interactive displays.
• Bidirectional IR control: Enables remote control signals to travel back to the source so devices can be operated from the display location.
• Wide device compatibility: Works with set-top boxes, PCs, game consoles and media players without special configuration in most setups.
• Includes power and IR kits: Ships with sender and receiver units, two power adapters and IR accessories for a ready-to-install kit.

Who It's For

This product is aimed at installers and home users who have existing 75 ohm RG-6 coaxial runs and need to deliver HDMI signals to distant rooms, outdoor displays, or digital signs without pulling long HDMI cables. It is especially useful where 4K resolution and low latency are required.

It is not the best choice for environments that require screw-type coax connections out of the box, unless the installer is willing to add a simple push-to-screw adapter, or where two-way Ethernet or PoE over the same run is required since those functions are not part of this extender.

Pros & Cons

Pros

• Delivers stable 4K@60Hz video over long coax runs with minimal setup.
• Backward compatible with older HDMI and HDCP versions so legacy sources will work.
• Included IR kit and power adapters make the kit plug-and-play for most installs.
• Low latency makes it suitable for live and interactive applications.

Cons

• The coaxial connectors are push type, not screw type, so an adapter may be required for some household coax runs.

Our Verdict

For anyone needing to run HDMI over existing coaxial cable, this extender offers a solid balance of range, 4K quality and low latency at a reasonable value. Installers will like the included power supplies and IR kit, while home users will appreciate minimal configuration. The push-style coax connectors are the only minor inconvenience, easily solved with a small adapter in most homes.

Frequently Asked Questions

Will this work with my 4K streaming box?
Yes; it is HDMI 2.0 and HDCP 2.2 compliant and supports 4K@60Hz, so most 4K streaming boxes will pass video through correctly.

Do I need special coax cable?
No special cable is required beyond a standard 75 ohm RG-6 coaxial run, but note the unit uses push-type coax connectors so a push-to-screw adapter may be needed for some wall plates.

Can I control the source from the remote display?
Yes; the kit includes dual bidirectional IR so remote control signals can be sent from the display back to the source.
