Review on J-Tech Digital 1X2 Wireless HDMI Extender 200ft: Full HD 1080p, Dual Antenna, HDMI Loop Output, IR Passthrough – Receiver (1080P 200ft) by Tom Reasons

My J-Tech transmitter is about twenty feet from my J-Tech receiver. There is only a plasterboard wall between the room where the transmitter is located and the adjacent room where the receiver is located. Apparently six meters is too far for this system to work properly. I tried every position of both blocks and nothing improved the transmission. I added two J-Tech extension antennas to try higher heights and more antenna positions. However, only an intermittent signal came from one room to the other. Even with signal transmission, there was a significant delay between the audio and video signals. The voice and then the lips move. I also hear that there is about a four to five second delay between a room with a signal on a large screen and an adjacent room with a small LED screen. The seller does not offer any solution other than return for refund. Need better technique and big improvements to sell in retail market.
