2 x 9dBi SMA 4G LTE Antenna, Omni Directional 3G/4G/GSM WiFi FPV Antenna WiFi Range Extender Booster HotSpot for Verizon, AT&T, Sprint, T-Mobile, Huawei and 4G Router&CDMA cellular services-SMA Female

These antennas DO NOT have SMA female connectors, nor will they connect to a device with SMA female connectors with any efficacy. The connectors on these antennas are RP-SMA male connectors. An SMA female connector has threads on the outside and a hole in the center for the pin of an SMA male connector to insert into. Most 4G/LTE broadband routers have SMA female connectors, requiring antennas with SMA male connectors (threads on inside with protruding pin in the center). It's hard enough figuring out how to operate 4G/LTE broadband router with any success already - any extra confusion is really not necessary. Just be careful when buying accessories for broadband devices and pay attention to connector formats and verify with pictures supplied in listings. These antennas are not described correctly in the item title or listing description. The pictures are the only thing that correctly depicts what connectors they actually use - which is RP-SMA male connectors.

Your information said it fit a Verizon Mi-fi, but these mi-fi's only have a charging connection, and there was nothing that connected the two together like it should have been. I was really disappointed when i got it. There were no directions which would even give me an idea of how to hook this thing up. I thought maybe i could go out and buy the connection, but i have no idea what to get. Your device has a round female connection, and a mi-fi has a small oval type connection. You need to do much better than this.

EDIT: I kindly received a refund after troubleshooting with the seller to no resolution.Attached these to my ATT Wireless Internet device, with pretty sub-par performance. Down speed seemed to be incrementally improved while upload speed seemed to actually take a decrease. Very minor dbi change. Wouldn't recommend for this sort of application.

These antennae raised our Verizon Mifi Home from 1 bar to 3 bars signal strength on both Data and voice. We are in a rural area in what was previously a marginal signal on cell phones and data. THANKS !!!!

Long story short, our company car travel in the city a lot, and there are equipment on it which need constant internet access to send data back to the server. We had try share data from mobile but that wasn't very reliable, phone reboot, internet drop randomly and stuffs. At last we found a dual sim 4G LTE modem that works quite reliable, but the reception wasn't that good because the stock antenna was tiny and short. After replacing with this antenna, i would say the reception improved by 70% at least.

I really like this antenna for a couple of reasons. One is the size is almost double of the standard size normally used on routers and extenders. I have included a side to side pic of this antenna (white) and the standard size (black). I also included a quarter for scale. Second is that not only is my wifi increased in distance but the signal is stronger at shorter distances. Would definately purchase these antenna again.

There is one room in my house I struggle getting a good WiFi signal. I got an extender and it helps a little bit. Once I replaced that antenna with one of these, the signal got really strong and I’m no longer worried about quality issues.

Can't say how they perform, because, I didn't look close enough at the picture to see they were the wrong connector for me. It's says sma male in the description but THEY ARE FEMALE. Just a heads up for any one who missed it in the picture like me.
