"Very prompt delivery and excellent product."


Don’t let the HDMI distance barrier hold you up. Use this extender to send your HDMI signal over a single inexpensive Cat5e/Cat6 cable up to 175 ft (60M).

How This Works

This kit comes as a pair, with one sender unit and one receiver unit.

  1. Simply connect the units together with one Cat5e/6 cable.
  2. Connect your HDMI cables from the sender and receiver units to their respective display or source device.
  3. Plug in the included power supplies.
  4. Your HDMI extension is now ready.

HDMI over Cat5

Does the Type of Cat5e or Cat6 Cable You Use Matter?

Since Cat5e/6 extenders (aka Baluns) work differently than typical ethernet networks, the quality of the network cable you use really does matter. The bottom line is that Ethernet networks have corrective measures in place to help balance the data load and prevent packet loss, while point-to-point extenders like this don't have this option. For this reason, using cable with extra shielding and extra-robust conductors (like our SSTP Cat6 cables made for extenders) to overcome any potential attenuation issues is recommended. You can read more in this article.

HDMI over Cat5e/6 Technology and the Limited HDMI Standard

HDMI over Cat5e/6 technology is relatively new and vital to scenarios where high definition digital signals must be extended over distances longer than 16 feet. HDMI's distance spec officially states that, beyond 16 feet, the signal is not guaranteed to perfectly arrive without some sort of active boosting. This booster will overcome this distance limitation while providing a more cost effective cabling solution as well.

For the best quality over lengths exceeding 100ft. Sewell suggests using Pure Copper Cat5e cable or Cat6 cable.

This shouldn't be a problem for most people, as the majority of Cat5e cable installed in homes meets these standards. Cat5e/6 cable, or ethernet cable, is a fraction of the cost of a long HDMI cable, mainly due to the different requirements of building these two different cable types. HDMI cable typically requires much more copper and is much thicker than Cat5e/6 networking cable. Also, many modern buildings these days are already wired with Cat5e/6 cable, making this solution by far the most cost effective and least labor intensive solution available.

Does this work through a switch?

Pros: Does this require point-to-point connection, or will it work through a network switch?

Pros: Very easy to setup and works very well. This is the second set of these I have purchased in the past year.

Cons: None.

Other: I had issues with the set that I received. I contacted tech support with my issue and they sent me out a replacement set the same day with a postage paid shipping label to return the problem pair. The replacement pair worked perfectly. I appreciate the good customer service and the quality of the product. The original set I purchased last year has work perfectly with no issues and I look forward to the second set to perform equally well.

Pros: By using the extenders we have been able to set up a projector that is 55 feet from the computer. We are not able to stream videos and seminars. It works very well.

Cons: It has some shielding problems when it comes to flourescent lighting. One in the facility has a bad ballast and it picks up the buzz from the ballast.

My Cat wire is split in a cabinet before heading back to tv. Will this work if an Ethernet connector is used to continue run?


As long as you have all four twisted pair terminated in a dedicated line from the sender to the receiver, it will work fine. Just please note that it can't go through a network or anything like that.
