To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I don't know how much to attribute to the intel AX200 wifi card versus how much effect these antennas have compared to others, but overall what I'm getting out of it blows away any expectations I had so I think both are incredible. I got these because it seemed like a higher dbi rating would provide better signal pickup. I have my PC on the other end of my house, using a normal wifi router (not wifi 6) that doesn't have external antennas (it just looks like a big modem) and that router is inside a heavy wood media cabinet under my TV--- all of that to say that there are lots of obstacles and distance between my wifi router and my PC using these antenna and it works great.
Awesome in every way except for installation. You will need some pin nosed pliers(electronics grade) a magnifying glass and a strong light. The connectors are small (like salt and pepper) but when they are lined up you can snap them together with gentle pressure from the pliers. When connected they work really well.
This worked really well with my m.2 Intel card and Jetson Xavier AGX. I connected via WiFi5 and 5GHz access point, and got much better speed than the mini USB WiFi dongle. Kind of annoying in this configuration with dangling wires, I may find a sturdy mounting mechanism later. I designed and 3D printed a plastic desktop holder for the antennas, that worked really well the first time so the antennas stand up and I can point each one as needed like on a router. Anyway, solid antennas and cables, this just worked.
Let me first say the equipment worked as intended. No scratches/dents/defects./etc.
I wanted to buy my own wireless card for the Dell Optiplex 3080 Micro I got from Black Friday. I then used these two provide the antennas since you need two: one for Wifi, the other is wifi/aux (read:bluetooth).
The RP-SMA connectors fit into the back of the small case which was my initial concern but the antenna side of that connector is just wide enough to rub against the other when installed properly. If you firmly but gently pull them apart, you can get the two antenna on there. It wont be screwed all the way on but will be enough to give me full bars on Wifi and BT.
Just wanted to make everyone aware in case you have one. I presume the physical specs are the same for all the Dell Optiplex 3000 Micro series so just keep that in mind.
