Review on J-Tech Digital Wireless HDMI Dongle Kit: 1080p 100' Range with IR Passthrough by Barry Taylor

The plan was to use this system to allow the HDMI camera to move freely when broadcasting live at the gym or other large venues. It connects when RX and TX are within 10ft of each other with no obstacles. Something in between doesn't work. It is cut off by a thin inner door. Tested in a small school gym at an open house. Even trying to keep the line of sight at less than 50 feet will fall out if someone appears to be within 10 feet of the camera. You'll need to get close to RX again to reconnect. In my opinion this only makes sense in static applications where the RX dongle and antenna are not obstructed over relatively short distances.
