Review on 🔌 5-Pack 16ft RP-SMA Male to RP-SMA Female WiFi Antenna Extension Coaxial Cable for Network Router, Bridge, IP Camera, Signal Booster, Repeater, Wireless Adapter by Mark Bullock

So, as the name of the product suggests, a wireless extension cable. But unfortunately I didn't notice until I tried to install them that the center pins were upside down. So in the lighter picture you can see my typical everyday Wi-Fi antenna. It has a regular everyday needle matched to these antennas. But if you look at the darker image, you can see that the male end also has a male center pin. There should be an outlet on that end so they can connect. The same with the other end, only in reverse. The center pins of these cables point backwards. Okay, back to finding others.
