J-Tech Digital 4K HDBaseT HDMI Extender Over Cat5e/6 Ethernet up to 230ft (1080P) 130ft (4K), Supports HDCP 2.2/1.4, RS232, Bi-Directional IR and PoC

The extender was easy to install and worked perfectly. When I needed tech support, they were easy to reach, looked up the tv I was using and quickly found the issue in a tv setting

I purchased several of these units to replace my old (RGB) component-over-CAT5 system. As my new TVs have transitioned to HDMI, my old system no longer supported the best picture standard (and some sets don't even have RGB inputs). Replacing the old RGB-over-CAT5 units was simple and the new system works well. So far, I am transmitting only 1080P content, with excellent picture quality. I intend to begin using 4K content and will update if anything is amiss. I like that the power comes from the transmitting end, so I don't need an outlet or power supply at the TV. One downside is that the old RGB system "lived" behind a wall faceplate, presenting a clean look at the TV. In reality, most installations effectively hide the HDMI receiver unit behind the TV set and a "blank" faceplate with a clean hole provides a transition for the CAT5 cable from the wall--which I prefer over yet more connectors in the signal path by using a CAT5 outlet plate. So far, I am using only the picture transmitting capabilities as the existing sound transmission system (goes to free standing local speakers, not the actual TV speakers) is better in so many ways than the speakers inside most TVs. My control system works as before and does not require the IR over CAT5 capability, so that feature was not put to the test either (though J-Tech includes all the cabling for remote IR connectivity!). Still, that additional flexibility is a nice to have for future expansion. Not well described in the product description, is that the system has blue lights in both sender and receiver, which are very informative to indicate proper connection of power and signals. Some black tape might be added to dim the blinking in a dark room. One other minor complaint is this version does not fully support routing a single CAT5 to multiple receivers and these receiver/transmitters are sold only in pairs. It is not clear which functions would be disabled and for now, this does not impact my system. J-Tech has other models which support multiple receivers from a single CAT5 line. J-Tech technical support was excellent and very helpful in my rather complex situation. A final comment is that the quality of HDMI cables varies--even ones claiming to be HDMI2 or 4K compatible. I had a few problems at installation including 4 J-Tech pairs, and EVERY issue was traced to a bad HDMI cable. You will need a several HDMI cables--buy the best--and then swap suspect cables around till you find the bad one(s).

These have been great at our church to run our projector which is roughly 100' from the computer. I can see the blue light blinking from the sound booth which tells me it's talking to the other end. I love the round power cord as well. The previous Blackbird extender had a strange power cord that you could reverse and bend the pins. Another thing I noticed about the J-Tech extenders is that I no longer have to power the computer and projector in a certain order as with the Blackbird. These just work!

Edit/update: I was able to get it to work when I switched the source to either a blu ray player or my PC. So the issue isn't my tv or the cables. For some reason, the j-tech will not transmit FiOS to my tv. I did finally get some signs of life from their tech support but it took more than a week for each response. Finally, because my window to return was closing, I had to send it back. I purchased another brand that was fifty $$ less and it works perfectly with FiOS. Great picture, great sound - and the IR for the remote works much much better than the J-TECH. Overall, a very disappointing experience w/ J-Tech. Background: Attempting to broadcast FiOS in 1080i over a 15-20' dedicated Cat5E cable run to my HD TV. The FiOS set top box (STB) info such as menu or guide will display fine. But when I select an actual program to watch, the tv only displays a solid blue screen. I tried setting the STB to different display settings (720P, etc) but same issue persists. And if I connect the STB directly to the TV (eliminating the j-tech components) using the same HDMI cables, it works fine. I submitted a detailed ticket to J-TECH and received back a zendesk confirmation that my support request as been logged. Nothing since.

Been using it for a month now to connect a projector to a home theatre system. Zero drops/glitches/handshake failures, very good. Delivers a full 4KHDR signal. The only "con" is that some devices don't seem to think the 4K signal is possible and you have to manually set it. Like on first connect the Roku defaulted to 1080i and I had to set it to 4K in the settings. Now this could be my AVR or something else, but it's just something to keep an eye on.

The J-Tech Digital 4K HDBaseT HDMI Extender is exactly what I needed when I had to extend a video signal across a long distance—without the hassle of running multiple HDMI cables. Setup was simple: just connect the transmitter and receiver with a Cat6 cable, and it worked flawlessly right out of the box. The video quality is crystal clear, even at 4K, with no lag or signal drop. It’s a lifesaver for clean, reliable AV setups in home theaters, conference rooms, or church AV systems. If you need to send HDMI signals far and want something that just works—this is it.

Seems to work flawlessly. I appreciate that the main unit supplies POE so not need for wall power at TV. It’s one less thing to deal with.

We have a monitor in our kitchen that primarily displays views from several of our outdoor cameras. When a game is on or people are over we'll sometimes switch the input to show that picture - all this was setup in 2012 and at the time 1080p was the going thing. Over the years various components were upgraded and the HDMI cable that was in the wall (about 40FT) would no longer pass a 4K signal - it would cut in and out. I had run CAT6a so I decided to try running the 4K signal over an extender. Ordered this J-Tech kit and it worked perfect - just plugged it in and everything came up - zero issues. My wiring was already terminated for T568B - did not have to change termination. I do like that the receiver is powered from the main unit - saves another wall-plug where this is located. Not using any other features other than video so can't speak to that (even the audio is all over external speakers).

who ever is reading this, do not buy anything from Global Hub or from Amazon, they are really unprofessional. I ordered this product and a faulty product was delivered to me, i returned this to Global Hub, they send me an other product which was nothing but the same product packed in a different box. I have been talking to Global Hub for 2 months, a post that they don't answer any of your calls, with a desperation I reached out to Amazon, they took the complaint to refund on 15th April 2020 and till date no action has been taken, now they come back to me stating it is 90 days you are not eligible for a refund. I have been trying to reach them and they conveniently delete all the emails, calls and state nothing was done. They should be ashamed of cheating their customers.

This extender works perfectly with Australian Foxtel IQ4, using only 1 Cat5 LAN UTP cable. The IR repeater functions perfectly also. The only negatives to speak of are that the units get relatively warm, requiring adequate ventilation, and the power adapter only comes with a USA 110VAC style plug (interchangeable, but no Australian version included).
