Maswell 4X4 MIMO Antenna 5G, Up to 6dBi, 600-8000MHz Omni External Antenna for 4G LTE 5G Routers & Gateways​​ for T-Mobile Verizon AT&T, WiFi 7 Ready, Homes and RVs (Full Kit)

We tried multiple antennas trying to get them work with AT&T signal. This offered the best connection. It is very compact, but works much better than other brand names. We use it to supply backup cellular connection to our network.

My internal Antennas worked better. I tried all cable combinations, like suggested by other reviewers. I decided to return.

Great product this far great Bill quality great signal very easy to install great functionality

Versatile booster, quality materials, simple setup:This booster is unique compared to others I've owned in the past because it's able to boost both cellular and wifi signals, whereas most other models I've seen can only do one or another. This item is great for patchy service areas where the wifi router isn't as strong as you'd like it to be. The setup does require a bit of time since you have to mount the plate and screw it in, but compared to other similar models it's very standard and doesn't take too much time from start to finish. The materials used to construct the device are pretty sturdy and it's adequately waterproofed for outdoor usage. The signal this provides is also clearly a big upgrade and definitely does boost the connection quite a bit.Overall, this is a good product and I would recommend.

(First photo with low speeds is before, second photo with higher speeds is after the antenna). I would say if your trying to get an advantage over your internal antennas this is the way to go with lossless MSA extensions on it.We probably tripled to quadrupled our speeds most of the time. Unfortunately the directions are junk with this unit and there’s some info basic first time users should know.Cons- this does not boost Band 41/n41 or 71/n71 which are T-mobile high speed signals! Also the antennas are not labeled 1-4 so you have a lot of guess work to hook this up properly.1- the antenna wires are not labeled and there’s 24 variations you can set them in on your wireless modem. 2 of those setups gave me 3mbps download and less than 1mbps, but after labeling the wires 1-4 and experimenting the variation (2,3,4,1) gave me speeds of 90+ download and 20mbps average upload.2-it’s omnidirectional which grabs signal in an upside down pyramid shape but only directly above the units top. It’s only semi-directional if you point it sideways in a direction you want towards a tower.It’s great for cheap use I just upgraded to a waveform quad pro when I found one for under $250 🤷‍♂️

No matter how I connected wires the speed did not improved. And it's not easy to keep switching wires around.

Sent mine back -- made NO difference. No instructions for connecting 4 wires to my gateway -- does it make a difference which goes where? All 4 looked the same on the antenna. Too many possible configurations to try. Won't buy this again.

I've never heard of Maswell Cellular, but as a T-mobile Home internet user, I've come to find antennas like this to be very critical in ensuring you get the best signal, and, as a result, the best speeds you can. This advertises being able to do 600 MHz - 8.0 Ghz, which is a pretty good range. This easily hits all the main bands that are critical for T-mobile, including N41, N71, and N25. It also gets the 4G bands B66 and B2 that, at least in my area, and the best to ensure a good signal with NSA 5G.The antenna itself is smaller than I anticipated. It's really about 5-6" with every dimension. It is a cube. I have not mounted mine outside, which, of course, is the ideal location. We literally just had snow, again, last week here in Utah in early May. I will probably mount it eventually, but, for now, my tests have been inside my home. It is pretty easy to use this though, you connect the SMA wires to the antenna, and then to your modem SMA ports. Pretty easy. Since this is 4x4 MIMO, it should be able to provide pretty good speeds.In comparison to my Suncomm SE06 modem with its built-in antennas, I typically get high 300 Mbps down and around 50 mbps up with NSA. SA gets me closer to 500 Mbps down, and 30 Mbps up. After connecting this, I would get closer to 500 Mbps down and 100 Mbps up with NSA, and 700 Mbps down and 50 Mbps up with SA 5G. All in all, that is nice. It improved my SINR from around 8 db to 14db. All in all, a pretty solid update. I'm sure going outside will allow me to see even better, but I don't really have a pole to mount it to yet either.At $158, this is priced pretty well, Waveform does have their Quadmini that is cheaper, and includes a cable that makes it easy to run cabling through a window. Of course, that same cable could work for this too. Going to $199 you can get Waveform's Quad Pro, which, in my experience, has been the ultimate antenna. This one is pretty darn close though. I'd certainly recommend this due to the price and speed/metric increases I've seen.
