Review on Bingfu Dual Band WiFi Antenna (4-Pack) for Enhanced Wireless Network Performance and Surveillance Systems by Chris Russell

This was my second purchase. The first order didn't work out. I used them for the wireless adapter. My goal was to increase profits. Unfortunately they didn't work. When I connected them to my adapter, the signal level deteriorated. i think i know why These antennas are adjustable in two axes. There should be an adjustment on the third axis and they will be able to focus the signal strength to the area where it is needed. Consider a flashlight with a reflector. The top and bottom left and right are far in front of you, but to look behind you need to be able to turn around. This product lacks that ability in its design. It's a shame as it is a well made product. What's even sadder is that I had to send them back because they didn't fit me.
