It's just an HDMI Extender Cable
Reviewed in the United States on September 25, 2017
Search on "HDMI Extender Cable". There is nothing magical here. It is not a "WiFi Signal Booster" per se. I needed one to get my FireStick out from behind my TV for repositioning for better wifi reception. So it's a "signal booster" in the same way your legs are a "Heater Booster" when they allow you to walk closer to the fireplace.
And note that you still need to have your power cable extending just as far as required. And don't fall for any gimmicks. This is a digital signal cable: The ones and zero's don't really care about gold-plated connectors and braid as long as the internal wire is good from end to end. So the cheapest one is likely as good as the most expensive.
