Waveform QuadMini: 4x4 MIMO Low-Profile Antenna Kit | External Antenna for 4G/5G Routers & Gateways | for T-Mobile Home Internet, Verizon, AT&T | 10’ SMA Cable, U.FL Adapters, Window Entry

Title: “The 4x4 MIMO Beast That Tamed My Dead Zones” Review:I grabbed the Waveform QuadMini because my home office was basically a Wi-Fi Bermuda Triangle — even the neighbor’s cat had better bars than me. This external antenna is no joke. Four separate MIMO feeds working together means you get a real signal boost instead of the snake-oil bars you see with cheaper junk.Build quality is industrial-grade — feels like you could bolt it to a spaceship if Elon called and needed better Starlink. The cables are thick, weather-rated, and clearly designed to last, not fray after one season in the sun.Once connected to my 5G modem, I went from barely one bar to full-bore download speeds, stable enough to stream 4K and upload giant files without rage-quitting. Installation is about as easy as any antenna can be: find a spot with line of sight, aim it, secure the brackets, and watch your signal bars multiply like rabbits. Pros:✔️ 4x4 MIMO for real performance gains✔️ Built solid enough to survive a hurricane✔️ Excellent cable and hardware quality✔️ Fixes dead zones for good Cons:➖ You might discover the rest of your network is now the bottleneck➖ Requires a bit of aiming to get peak results Bottom line: if you want to transform “Wi-Fi wasteland” into “streaming paradise,” this Waveform QuadMini is worth every penny — you’ll wonder how you ever put up with bad reception before.

Pros:1) Works really well for such a simple device (the "antenna" is just a small rectangular dish)2) The kit had MULTIPLE tools to hang this thing—either outside strapped to a pole (I hung it around my downspout), drilled into a wall, or inside fastened to a window or on a desk. Installation was versatile.3) Noticeable boost in signal strength. This really does have multiple variables going for it, but once you do some research and point it towards the nearest cell tower, you should get a decent boost in signal strength4) A lot of instructional material, FAQs, even on-line videos made installation pretty easy. After strapping it around my downspout, I used the window extension to run the lines underneath my window (so that it could remain closed), and then connected those wires to my cell modem5) Obviously with 5G, there will be many variables to speed, but on average, I consistently got about ≤ 100 Mbps down and up to 10 Mbps up; now I get about 150-160 Mbps down and 20 Mbps up. Just this morning (5/25/25 at 07:09) I got 210.66 Mbps down and 55.64 Mbps up.6) Customer service—I had someone texting me soon as I started setting up, making sure I wasn't lost, so that was nice.Cons:1) Depends on setup obviously, but it can be kind of complex if you're looking for the best signal (ie, installing the antenna outdoors and running a line to your cell modem). I do wish the window extension line was a bit longer, by like six more inches, as my window is thick and the extension barely made it for me to close my window.2) This is not on the product itself, but I have the T-Mobile Sagemcom Fast 5688W 5G Wi-Fi 6 Internet Gateway, and you have to bust that thing open to access the internal connectors. OMG that part sucked donkey balls.

Emery easy to install and had enough impact on signal to keep my video meetings and all streaming needs solid.I live in on the fringe of service and over the years have tried satellite services and multiple cellular companies. Now more cellular internet providers have 5g unlimited plans that rival cable or fiber or even less expensive. Easy coast forests get dense and dark during the summers. I forget about the service impact until around late March each year. Over the winter I switched from a 4G RV plan to a home T-Mobile 5G plan and jumped from 40ish mps to well over 200 download as well as I did not connect the 2x2 mimo antenna I had installed on the roof years ago. Then warmer weather. With the sneezing came choppy video calls and slower downloads. At first I thought the worse of a now popular/congested system then the aha moment. I moved the modem to an upper window location from the mechanical room and it greatly improved then held it outside the window on a temp mount and I was back in business. The Waveform mini reflected that bump in service exactly. My download speeds were back to what I have during the winter or better (300-500 depending on how the wind blows) and uploads from 1-2 to stable 6-12. Most importantly ping dropped from 89 to 39 and hasn’t changed. The data doesn’t reflect the real world use and experience. Work from home is now possible again with out concern and I’m a happy camper.Some things I didn’t know but guessed - the attached antenna cables are 3’ long and if you want an easy install get the kit with the window pass through. It is incredibly important to get the antenna OUTSIDE of the house even if on the other side of the same window pane.

Review was updated from 3 to 4 stars because of tech support.I received the product ahead of time. hookup was easy, I tried it out but little difference in download or upload speeds. My internal antenna I was getting on the average from 150 to 250 DL 30 to 40 UL when I added the external antenna it was about the same , tried it in several locations in my upstairs apartment. I was hoping I would get much better speeds. If I was closer to a cell tower then maybe the speeds would be better. I't a possibility it could be a defective unit. I may in the future purchase another but just the unit no cable.
