Review on Bingfu WiFi Antenna Extension Cable 2-Pack - RP-SMA Male to RP-SMA Female Bulkhead Mount - 16.5ft RG174 Cable - Ideal for WiFi Routers, Security IP Cameras, Wireless Network Cards, Adapters, Lora & LoraWAN Gateways by Brian Page

Works as advertised. I used one of these to remotely locate one of the two antennas on my wireless CCTV DVR. This allowed three wireless cameras to be securely connected. After A LOT of work the system became stable. There were too many competing WiFi signals. Pretty typical for a residential application if you ask me. And for what it's worth, I will NEVER install another wireless camera system again. POE cameras are exactly what you need! But this cable helped salvage a nearly failed install, so I'm a happy customer!
