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.

Got this and connected it without permanently installing it. What I immediately noticed is that my signal stabilized. Initially, with the antenna being inside of a log cabin, there was little to no speed increase over my best speed test but the speed was far more consistent, maintaining better up and down performance instead of the wild swings in performance I'd grown accustomed to. With just a T-Mobile gateway I was getting from 90-320 down and 2-15 up but it was all over the place. With the WaveForm (inside) I'd get 220-280 down and 10-30 up but these connections were far more stable. I'm pretty far from the tower, surrounded by old growth forrest, and in the mountains so this is a difficult situation to be sure, but with the antenna installed outside on a pole just above our roof, I'm in the 480 down 18 up range most of the time. It's important to note that your results may vary. Distance, environment, construction method of your home, area interference, UFOs... These connections can be difficult, but... The support starts the moment you open the box and scan the QR code. You don't reach out to them. They start texting you. Don't have a sec to respond? No worries. This exchange seems to stay live from the beginning and you can just text them back whenever you have an issue or question. It's kind of remarkable. I'm building a mountain resort and don't have time to deal with making this antenna work. Support has stuck with me for months, occasionally checking in to see how things are going sometimes weeks after I haven't responded. NOT IN AN ANNOYING WAY like they're trying to sell me something. They just seem to be genuinely concerned with getting the most of their product and I'm all about it. And just in case you're wondering, yes! This continued well past the return window for the product purchase. I still have other recommendations from them to try as I'd really like to increase my upload speeds a little, but I know they've got my back when I'm ready to work on it again. They're doing all this right and I'm happy to support them in that endeavor.

Size: Complete Kit w/ 10' Cable & Window Entry
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 strength 4) 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 modem 5) 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.
