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

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.

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.

The Waveform Quadmini 4x4 antenna has been excellent. It significantly improved both the speed and signal of my T-Mobile 5G home internet. The customer service team was also very helpful in guiding me to the best placement and direction for the antenna. Overall, I'm very satisfied with the purchase.

Easy setup, including a personalized custom map from the manufacturer with locations of nearby cellular towers, and text message support. The antenna works well and significantly improved connection speed, signal strength, and S/N ratio. A good investment for those who depend on cellular internet service.

Junk, bought this to have a backup external antenna to look at other towers when my local goes down, local tmobile tower is in eye sight of my home (2 blocks away), using this antenna brings download speeds down by 200mb and uploads into single digits. Using the standard antennas inside tmobile base router works better.

This did not improve my signal on my Rogers 5G Home Internet with the Nokia Fastmile 3.2 hub. The technicians were very helpful in troubleshooting, but ultimately this was not an option for my situation. For those considering this to help with signal on the Rogers rural internet plan over 5G, be aware that the Nokia modem/router that Rogers uses has 8 internal antennae, and determining which 4 to choose to swap out is a bit of a guessing game since none of the antennae as labelled for certain bands. Waveform does not have a guide for this specific modem, so you need to find this information online. The Waveform technician suggested I buy two (2) 4X4 MIMO systems and connect to all 8 ports, which is financially and technically onerous, with uncertain results. I've given this 4 stars since the issue isn't this product, but my specific circumstances. The product was high quality and the support was incredible.

Excellent product that is a great improvement on our current situation. Living on a boat signal is very difficult to achieve. Our Landline gives 21mb, without an antenna our mobile signal was up to 30mb which was an improvement but with this kit our signal jumped to an impressive 107mb. Hopefully no more buffering when watching movies and live sport. Beware the customer service advised by contacting Waveview in their booklet though. Very pleasant on the phone but didn’t deliver! We had a part missing which they were resolving. Ended up buying the missing part ourselves as we didn’t receive the part as promised.

Using a monile phone at at home on Three network, fastwst phone alive, achieved on 5g, several MBps down, less than 1Mbps up. Using a Three network NR5103e mobile router, internal antenna, average download speeds of 60Mbps and upload 5MBps. Connecting this external antenna, and placing it just outside of the window, loosely placed on a ledge (i will stick it down eventually but no rush, the 2 occasions when it fell backwards i was still receiving 690MBps) pointing it in the general direction of the Mobile transmitter, it jumped to 730MBps download and 90MBps speeds! Can't imagine what it'd be where there's a better signal anyway! I'm in a virtual dead spot for all mobile networks. The engineering of this antenna is genuinely hardcore! Looks kind of cool and hi tech as well, and will not look out of place on a trendy desk, it's smart and also small due to the slim, minimalist (and well engineered) design. There's a qr code on the box saying scan me before opening, and it takes you to the shortest form ever to get them to send you a personalised site map, and recommendations on siting your antenna according to where the nearest mobile towers are. Best external antenna I've ever come across, and I've used many of them. First I'm genuinely now brand loyal to!

Got this to add outdoor antennae to me GLX-3000 4/5G router setup in the UK. Used the window mounting suckers to place on living room window and point at 5G local masts. Went from around 80 meg download to around 120-200 meg immediately. Super-stable connection and easy to install via flat window entry cable to connect to router indoors. Get one!
