4x4 MIMO Omnidirectional Low Profile Wide-Band 4G LTE 5G Magnetic Base External Antenna for Boosts Performance of 4G/5G Routers Gateways Hotspot Verizon AT&T T-Mobile RV Home Internet, Slinkdsco

My signal went from 20 to 30 Kbs to over 150 Kps. I use it at a remote site for transmitting Power Station data and Surveillance Camera's video content. Works perfectly for increasing the signal. Great purchase.

While the cables this come with are short, and this may have been the problem. It did NOTHING for signal strength returned it.

This works!

I picked up this long-range 4G LTE antenna booster to use with my cell phone signal repeater setup—mostly for RV trips, camping, and just getting better signal in general on the go. I actually built my own custom mount for it using a huge industrial magnet off an old CB unit and a metal L-bracket, then secured everything with epoxy and screws. The result is rock solid; I haven’t tested it on my vehicle roof at highway speeds yet, but just from the weight of the magnet, I doubt it’ll move. So far, I’m impressed. The signal is stable, and I left it outside overnight in the snow, and it didn’t rust or get damaged. Still works just as well as day one. In terms of performance, this thing definitely increased my signal strength compared to using a cheap antenna. I used to get maybe 8 dB, but now I’m getting 18–20 dB readings on my booster, and that’s a big difference. I’ve also noticed my internet speeds are better, even when I only use the outdoor antenna (haven’t fully dialed in the indoor antenna situation yet). Just know, this isn’t magic—it won’t give you signal in a true dead zone. If you’re in a very weak area, the only way you’re going to get any kind of improvement is if you mount this thing as high as possible (like on a pole). For folks who already have some coverage but just want to boost a weak signal, this antenna is perfect. One tip: make sure your indoor antenna isn’t too “hot” or high-gain, or you’ll run into feedback issues (that’s my current struggle). I’m waiting on a 3 dB indoor antenna to hopefully solve that problem, so I can keep everything close together and really maximize speeds. The cable that comes with it is low loss, which is exactly what you want for good data throughput. Also, the price is hard to beat for a setup that includes a real low-loss cable. If you’re planning to use this with a cell phone booster, make sure you grab the right adapters (N male to SMA female in most cases) because the included connectors might not match your booster out of the box. To sum up: Signal boost is real—went from one bar to two or three, and saw speeds double in some cases (e.g., from 24 Mbps download/3–5 Mbps up to 40 Mbps download/12 Mbps upload at best). Build quality is solid, stood up to snow and cold, and the bracket hasn’t rusted at all. Not a fix for true dead zones, don’t expect miracles, but if you have weak signal, it’ll help a lot. Adapters are a must; make sure you get the right ones for your gear. Feedback issues can happen if your indoor antenna is too strong, get a lower-gain indoor antenna if needed. Overall, I think it’s a great deal. Just be realistic about what it can do and take some time to set up your antennas and adapters right. If you tinker a bit, you’ll get a really nice bump in 4G LTE speeds for not much money.

Didn't help with my signal at all. I even purchased some additional extension cables to try mounting in many different places, but alas - never got better signal than when using the internal antenna on my T-Mobile home internet gateway...

Did not help with signal strength.

This is exactly what I needed. It brings in a stronger signal.

This did nothing to help my t mobile speeds. I love close to a tower and normally get very good signal. I connected this and it went to just good. So it actually made my download speeds worse than it would have been normally. Not really worth it, and spending more than that is also not worth it. I get 100mbps download now, and that's enough for me. Maybe it'll be better for someone else. The magnet isn't as strong as it claims either.
