WiFi Antenna Dual Band 7dBi 2.4GHz/5.8GHz with RP-SMA Connector for Wireless Network Router USB Adapter PCI Card IP Camera DJI Phantom Wireless Range Extender FPV UAV Drone

I tested these antennas against the stock antenna that came with a Gigabyte desktop WIFI kit using an Intel 8260 mini card for 2.4,and 5Ghz and Bluetooth 4.2. This kit is the new 802.11 AC spec, and needs a 2Rx2T (two time receive and two times transmit) antenna that also supports bluetooth 4.2 spec.Performance of the Gigabyte antenna is good, it maxes out the 100Mbps Optimum cable service I have over wifi. Tests with both antennas showed 115Mbps down, 37Mbps up on the 5Ghz connection, and a little less on the 2.4Ghz connection. The desktop is in the next room from the Optimum router (802.11AC spec) so results are good with both antennas.There is a significant difference in Link Speed,, Signal Strength and DBI between them that makes me think the TECHTOO antennas will perform better when farther away or signal starts to degrade.TECHTOO 5Ghz Link Speed 520 Mbps, Signal Strength 80%, DBI -60. (with DBI lower number is a stronger, better signal)Gigabyte 5Ghz Link Speed 390Mbps, Signal Strength 80%, DBI -65 (still a good signal, but the TECHTOO has better reception)TECHTOO 2.4Ghz Link Speed 144 Mbps, Signal Strength 99%, DBI -39. ( very strong signall)Gigabyte 2.4Ghz Link Speed 144Mbps, Signal Strength 93%, DBI -55 (still a good signal, but the TECHTOO has better reception).So, the TECHTOO signal numbers show that they are pulling in a better quality signal than the stock Gigabyte antenna. The farther away ore more radio noise there is the TECHTOO should perform better. And the TECHTOO has 130Mbps faster Link Speed, meaning if I had faster internet service, the TECHTOO antennas would have better/higher speed tests than the Gigabyte.Another very important item was the Bluetooth 4.2 performance. Photo's loaded faster from my Samsung S5 to the desktop with the TECHTOO antennas through bluetooth. And there was no problems with the Intel 8260 mini card picking up wifi signals when bluetooth was on (a problem when testing regular dual band 6dbi antennas). All features of the Gigabyte mini card worked with the TECHTOO antennas. So if you have 802.11AC spec router and Desktop PCIe wifi cards these antennas are the way to go.

I have over 25 years of professional, enterprise-level (big company) IT experience and specialize in security, data centers, networking, wireless (wifi), mobile devices, and desktop/laptop equipment provisioning and support (I.e.., I manage multiple IT departments for well-known companies). With more and more IoT things (wifi lightbulbs and switches), I was looking for upgraded antennas to replace the stubby little ones on a high-end wifi setup (4x4 MIMO, 802.11AC, expensive business-grade brand- had to use adapters for these antennas to screw in). Before swapping out the stubby antennas, I walk around taking measurements with a Samsung S9 Plus, measuring speed and wireless signal strength at various challenging places inside and outside my house (2000 sq ft on a 6000 sq ft lot; very typical mid-70's southern CA home). --Tests were repeated to ensure accuracy-- My internet service is Frontier fiber with 500Mb up and down; the Samsung S9+ @ 3 feet away will max out around 275Mb/s. Here's what I found... (all test are at the 5Ghz band; it's much cleaner (less noisy) and faster than 2.4Ghz, but the also weakest signal option).Pic #1, original antennas: Worst-case location - Outside, far front corner, end of driveway by the street: Poor signal (about -84 dBm) with 7.89Mb down/3.37Mb upload.Pic #2, Techtoo 7Dbi antennas: Same Worst-case location - Outside, far front corner, end of driveway by the street: Poor signal (about -81/82 dBm)- HUGE speed improvement- 28.8Mb down (365% increase)/ 10.2Mb upload (300% increase).Pic #3 shows the wireless signal strength; the top 2 "Hunt" listings are mine.In every location I checked, the signal "strength" remained the same, or improved only very slightly (1-3 DBi); not enough to make any material difference. HOWEVER, the *quality* of the signal improved dramatically; the speeds were 2-3x higher across the board and the connection was rock solid.(NOTE- I am an IT professional, not an electrical engineer; these tests were meant to be accurate and repeatable without going totally overboard).

I used these antennas for a replacement for the ones that came with my motherboard. I thought it would be fairly plug and play and it was. The only issue is that my motherboard's connectors were too close together so I couldn't fit both antennas at the same time. I'll file down the bessels a little bit and I'm sure that the second antenna will fit just fine. The download speed did improve a lot for me though. On steam it went from a maximum of 16 mbs to 22. This was on the 5 ghz band. In short I can't wait to see what two antennas can do and all in all they are decent. Worth the money

I have a very powerful editing laptop away from my modem. If I gained I would have preferred ethernet cable but unfortunately I don't gain so having the most hard line connection is in a priority. I use my computer mostly for content creating. It was a bummer having a 4.7 gigahertz 32 gig ram 4 TB hard drive not be able to connect to the internet due to lack of signal. I placed one of these on the device and was able to secure an additional 5 bars of service to my delight. To give you an example of where I came from,my connection was so low that my computer wouldn't even connect to my own modem. Now not only do I have four to five bars consistently, I'm able to get 70% of the speed my ethernet cable would naturally achieve. The best part is I'm only using one of the antennas, which means I will be able you know antenna for the future if anything happens to the original because I'm able to get 2.5 and 5G off of 1 antenna.

I couldn't use both antennas, my motherboard had the antennas too close together.
