Review on 📶 Eightwood 2.4GHz 5GHz Dual Band WiFi Antenna - RP-SMA Male Antenna Magnetic Base for PC Desktop Computer, WiFi Wireless Router, Mobile Hotspot, PCI PCIe WiFi Card, External WiFi USB Adapter by Justin Buck

I was so sure it would improve my WiFi signal depending on where my router was that I kept using it for two months despite all the evidence to the contrary used. I kept moving the base and adjusting the position of the antenna and nothing could bring my signal strength back to where it was before. Eventually I unplugged it and reinstalled the original 3 antennas that came with my Dlink router and immediately my signal improved. I think it was a relatively inexpensive way to find out that what I had before wasn't that bad.
