PortKeys 60GHz Wireless Video Short Distance Transmission SDI/HDMI Broadcast Transmitter/Receiver Supports Full HD 1080P,Compatible with All Brands Gimbal and Stabilizer

I've tested it out in a real run and gun shooting, with gimbals, slider, indoor, outdoor etc. The biggest flaw for me is that you have to be (stand, run, etc) close to the transmitter to get signal. The safe working distance is 2, max 3 meters, but ONLY if you have turned the transmitting side of the transmitter cube towards the receiver, otherwise the signal is dropping out continously. It helps if you change batteries more often, with full battery the transmission gets better. There are no classic antennas, so the receiver side of the unit always has to be faced towards the transmitter side of the other unit, and you have to always adjust it. But it's working, for this price you get the SDI capability, there is only a little-to-no lag, and the receiver is working all day even with a smaller power bank. And it works as a SDI-to-HDMI converter also.
