Works great on my PC. Solid connectivity with XFinity Wi-Fi 6 router using built-in motherboard Wi-Fi card. Definitely recommend. Use V-shape orientation for best results.

Does not work well with Raspberry Pi. Purchase to improve signal to raspberry pi, and it was worse than the antenna that my pi came with.

Bought a used PC and it was missing the antennas for the Bluetooth and Wi-Fi. Bought these to replace them. Despite how small they are they seem to do a pretty decent job. And they look quite nice since they're not huge and obtrusive.

These seem to work fine at 2.4GHz, no idea on 5GHz. I bought them because they are short and I needed something for a tight space. But beware, size is everything in antennas. So are they any good at 2.4GHz? probably decent, not great. I don't use them at 5GHz but they probably are fine there. Mechanically they seem fine as I'm using them for backup camera on a UTV and they've survived pressure washing and rugged trail bumpy roads.

Bear with me guys, I'm an electrical engineer.I have an internet radio that operates exclusively on the 2.4 GHz Wi-Fi band - it doesn't ever use the 5 or 6 GHz bands.The center of this Wi-Fi band is 2.437 GHz, which has a quarter wavelength if 3.075 cm. A quarter wavelength in size is the ideal size for an antenna. I measured this - as near as I can tell, the length of the active element inside the plastic is nearly spot-on 3.1 cm - PERFECT!Taking measurements, the signal strength with this tiny antenna was more than for a 5" and an 8" antenna. So, this small antenna could well be better than a larger one. It is for me!

Bluetooth and WiFi continue to work well (2.4 and 5.8ghz). Replaces the original equipment sharkfin antenna that came with my motherboard. WiFi AP and bluetooth devices are within reasonable distance of my PC so I have not tested how range was affected, but bandwidth performance remains the same after swapping out antennas.

I recently upgraded my WiFi setup with the 2.4GHz/5GHz/5.8GHz Omnidirectional Mini RP SMA Antenna, and it's been a fantastic addition to my network. This small yet powerful antenna significantly improved the range and signal strength of my router, making a noticeable difference in the speed and stability of my internet connection. It's versatile and works perfectly not only for my router but also for my security cameras and FPV TX transmitter, enhancing their performance across the board. If you're looking to boost your WiFi signal or improve your wireless devices' connectivity, this antenna is a smart choice.

There are perfect from SFF/ITX builds or open case designs. These are tiny but still pickup good signal given their size. My Test Bench bounces between 80-90% signal roughly 40ft from my router. Even with the slightly reduced signal I'm still able to record 850mbps download & 950mbps upload over these antennas. So just like the signal I'm able to achieve 80-90% of my gigabit internet.

um ein bisschen Ordnung auf den Schreibtisch zu bringen eignet sich der Stecker perfekt. Kein Wackelkontakt und sitzt fest im Netzteil bzw. Steckdose.

I used these instead of the external ASUS antenna for my SFF pc build. I don't see any signal drop (the pc is not far from the wifi router) and it looks pretty sleek without any visible antenna. I'd recommend.

Antenitas WiFi-Bluetooth para un MiniPC. Si quieres máximo alcance, busca unas antenitas más grandes. Éstas tienen una ganancia (especificada, no comprobada) de 3 dBi mientras unas más largas pueden ser de 8 dBi. Hay que vigilar, al hacer el pedido, que los conectores coincidan con las necesidades. Los hay de diferentes tipos.
