Review: Roll the dice! - Without disclosing my background, I feel more than qualified to write a review for these. That being said... They work. Very well. The router I placed these on needed six of them. The stock ones broke, and I decided to take a chance on upgrading, instead of just replacing. Of the places in my home that were dead spots, usually behind a thick wall or metal, about 80% now have a signal, and in most cases, a pretty good signal at that. They're not magic, and they're not perfect. They do feel like they're magic though 🙂 The signal also went much further. Almost double. I would estimate 25 yards minimum. However, for security reasons I would not recommend these for everybody, as you would not want to overbroadcast. For me, it's practically a necessity. If you have ever bought aftermarket antennas for a router, then you probably know it's 50/50 if they work at all, let alone work better than the OEM. We considered a range extender, but have had mixed results for various reasons. We considered a mesh network, but didn't really see the point in buying a new router, especially when Wi-Fi 7 is about to drop. The router was fine, the antennas were broke. The cheapest first step was to replace them with OEM, but decided to roll the dice and go for these as an upgrade instead. The bet paid off. These were everything I dared not hope for. I would definitely look here first in the future. I don't know if they'd work with all/your routers, or if I got all the luck, but they were a nice tight fit, I'd say even better than OEM. They don't flop around despite their size, and while I didn't open one up, it seems like they're legit and durable. In short, if Chuck Norris needed replacement antennas for his router, these are probably the ones I would recommend 🙂
Review: It works GREAT - but don't make my mistake - I want to start off my review by describing my set-up. It's an older tower, tucked away in a corner, underneath 6 boxes of stuff, on the opposite wall of my router. Total distance is not that far - but the wifi was 1 bar, and dropping constantly. Couldn't even get Google maps to load properly. I put these in and presto - I might as well be hard-wired! You will generally want your wifi antennae to be orthogonal / perpendicular - that is, 90 degrees to each other, and to the router. So, one antenna "up", one antenna to the right (or left); and if you have a 3rd antenna, straight back. Now, for the warning - most antennae can be adjusted by simply turning them a bit more, after being screwed on. That is because there are multiple points on the antenna that can rotate (the socket that locks into the card, and one about a hair above it that allows it to be rotated for the positioning mentioned above). These antennae are heavy - they use heavy material, and you can apply a LOT of force, without even trying. I actually overturned to the point that the nut in the wifi card, actually got stuck, and had now started to turn the wire on the card. To fix the issue, actually took needle-nose pliers to stabilize the nut on the card itself, untwist the antenna, and stabilize the connection with the card.. Don't just do it by feel - actually look at the connection, and make sure you are adjusting the antenna, and not overturning. I would absolutely buy it again, and just approach more cautiously. Wifi cards with antennae will outperform those USB receivers any day, and this item gives the supercharge you need.

### ⭐⭐⭐⭐ Used for PS VR2 controllers on PC
*by I***E on August 28, 2024*

I bought these antennas to help boost the Bluetooth signal from my TP-Link AC1200 PCIe card, since the stock antennas that came with the card were only about 5" or 6" long. These 1.3' antenna's help the signal so the PS VR2 Sense controllers track better. Before, the right Sense controller was very delayed and would randomly float away, after installing these longer antennas, the controllers no longer have any lag, and I've only had minor issues with the left controller skipping slightly on occasion, depending on if my body is blocking the line of sight for the signal. Nothing major, and definitely playable now, when it was unplayable before. If you get these for the same reason as me, your experience may vary depending on your room setup in relation to where the VR games are played.
