Dual Band 2.4 5.8 GHz WiFi Antenna, 5dBi Mini Omni-Directional RP-SMA Male Antenna 10ft Cable w/SMA Male to RPSMA Female Adapter for WiFi Router Hotspot Wireless Network Card

It worked to receive and pass through steel panels of barn to the extender located inside to provide Wi-Fi for my cameras to transmit pictures. It works just as I expected.

Done what it's supposed to. Smaller than I imagined.

Works great on my polebarn for a signal inside.

The antenna lead wire is not cemented or secured into the antenna puck and pulls out disconcertingly, there is no seal to the inside of the puck.

Promising in design, but quite lacking in practical application. Struggled to get a signal from just 60 ft away, in relatively clear space. The mounting nut can also be a bit cramped to use depending on installation location. But it did provide a good seal against the wall. Highly recommend some type of dedicated mounting box with extra space for your hands to fit during installation.

This antenna exceeded my expectations. I was struggling with weak WiFi signals in my metal shed, but after connecting this to GL.iNet GL-AR300M16-Ext Portable Mini Travel Wireless Pocket Router, I noticed a significant improvement. The build quality is solid, and the cable is flexible enough to route wherever you need. If you need better range or want to fine-tune your setup, this is a great low-cost upgrade.

I needed a remote 2.4GHz antenna to control a robot lowered down into a cave. This mates with the SMA connector on the transmitter, and seems to work just as well as the normal antenna. For a more normal application the antenna would mount directly onto a surface, and the adhesive rubber washer should prevent any seepage into the mounting hole. The included double male SMA adapter was a nice feature.

It's basically a small puck antenna, at the end of a long feed line, feeding very high RF frequencies, at relatively low power, so don't expect miracles. However, it happily handles my bluetooth devices in the same room, and connects to my Wifi in the next room over just fine, and that's all I needed. And it's nicely flush mounted on my desk setup instead of the janky plastic antenna that came with my motherboard.
