Review on 📶 Enhance Wireless Network Performance with TECHTOO 9dBi Omni WiFi Antenna: Ideal for Routers, USB Adapters, IP Cameras, and Range Extenders (1-Pack) by Jeff Alradwan

Well I don't know how to measure the results as I don't have a real RF spectrum analyzer but I did an event last weekend and had no problems with the Wi-Fi controller. Last year at the same event with standard antennas, I couldn't get my router 15 feet away without losing Wi-Fi completely. They're longer than the standard antennas that come with a standard WiFi router, but that's not a problem. They simply screw into the existing router ports and bam! Never lost signal all night in an auditorium about 25 or 30 feet from the router.
