9dBi 2.4GHz 5.8GHz Dual Band WiFi Antenna 3-Pack, Omni-Directional Wireless Antenna with RP-SMA Connector for Wireless Network Router, PCI/PCIe Card, USB Adapter, IP Camera

I like the sturdiness of them. They will stand up instead of flopping over like some other antennas do. They also stay at whatever angle you put them at.They did improve wifi signal strength, but not that much. Every little bit helps I guess and they aren't that expensive, so they were worthwhile.

I'm giving four stars because although it didn't work for me, it works better in some cases.These antennas performed noticeably worse than the standard antennas that came with my router (D-Link 880-L).I suspect these are more useful for people that use devices far away from the router, at the edge of the cell.My problem is too many people around me trying to use the same channel, So I was hoping to boost my signal a bit to get more bedroom, but it seems these antennas are not meant for that purpose.

These boosted the signals for my cameras just as expected, but remember that I can't enhance my nvr (receiver) antenna, don't know how, so the signal boost can't be much if it's just one end, and the equipment (cams and nvr) has their own specifications where you just can't boost their signal too much further than what they are designed for. So what if my wireless camera can now record 1080p vids from almost 200 ft away? They were designed for about 150-200 ft to begin with, so I did not really increase its distance more than 20 feet.I can boost the signal stronger if I figure out how to do that with an nvr, but I doubt that will boost it much more, maybe around 220 ft max. It was already at about 170+ ft before the boosting, so you can't expect the giant wire extensions you got from Amazon to extend much further. Reasonable increase will be reasonable.

This review is for:- ASIN=B07V71QK9M- Title="9dBi 2.4GHz 5.8GHz Dual Band WiFi Antenna 3-Pack, Omni-Directional Wireless Antenna with RP-SMA Connector for Wireless Network Router, PCI/PCIe Card, USB Adapter, IP Camera"- Brand: Queenti- Ships from AmazonAmazon- Sold by MenkeyMenkeyWhy should one buy this kind of product?- Your previous antennas are of lower dBi. Lower dBi antennas have a more omni-directional dipole radiation pattern which is fine for broadcasting a signal in a big sphere.- You want to flatten the pattern significantly to broadcast over a longer horizontal distance at the cost of vertical.Positives:- Price is excellent; ordered twice (6 count).- Build quality is fine. Used in indoor application (x4) and outdoor application (x2).- Range is significantly improved compared to my previous 2dBi antennas (omni-directional).- Gain measured using simple equipment and apps shows about 9dBi gain as advertised on 2.4GHz and slightly higher gain on 5GHz on a path with clear line of sight with no walls/obstructions. This behavior is expected for dual-band antenna.- The dipole radiation pattern is now nearly flat and reaches a significantly longer distance instead of being wasted above and below the antenna. Coverage pattern was extrapolated from the gain measurements described above.Negatives: None.

TP Link C7 Archer. I was having issues with 2.4 GHz being a bit slower when further away, I wanted to try different antenna to see if that could help the signal.Signal strength did not change dramatically. Yes it was marginally stronger -50 vs -55 but they did not help access.WiFi Router is on 2nd floor, issue on 1st floor.I ended up repurposing an older router as a wifi bridge moved to a location that allowed stronger signal to the area that needed it.

This is an inexpensive way to upgrade your WIFI routers. I used it on the popular Asus RT-68U and it boost the signal by 3-6db using my phone meter around the house. A 3db gain is doubling the signal strength. A so called new WIFI6 or AX router may not even give that much a boost let alone 6db! I know this because I also own three AX routers. While they are good for AX to AX connections, when it comes to AC or even N connections, their signal strength often are not what one is hopping for. BTW, many more expensive outdoor WIFI security cameras also use compatible antenna connectors. If your signal is weak and you are not willing or unable to run euthenist cable to hardwire the camera, these antennas is also a good way to boost the signal of the camera.

I put these on my security cameras hoping to make the wireless connection better but they didn't help.

I have a TP-link archer C7 v4. I am also approxinately 300 feet away from an xfinity wifi hotspot, and behind 3 or 4 concrete walls.The original antennas barely picked up the 5ghz band of the hotspot, and had frequent network drops. I regularly saw 17mbit/s theoretical connection speeds.With these antennas, I have a SNR of about 30 as opposed to 5. I wasn't expecting this imptovement at this price...I reccomend these antennas for anything that they'll fit. They are huge, and might be a bit topheavy, but they WORK! Use stickytack or double sided tape to stick the tips to a wall.
