SANQINO Cell Phone Signal Booster for Home, Dual Band 850Mhz/1900Mhz Mobile Repeater Amplifier, for 3G Verizon, U. S. Cellular, T-Mobile, AT&T (Yellow)

We recently moved into a new home in a rural area of the Pacific Northwest, and the only cable Internet is DSL at about 1.5 Mbps, not enough for streaming. Our cell service is with Verizon, and I tried to use my Samsung S7 Edge as a hot spot, which worked ok, but was very expensive. Signal strength showing on the S7 was in the -105 to -100 dB range, pretty average, but we did not have dropped calls and communication was very clear. I also bought a Franklin R910 to try as a hotspot on the Sprint network. It worked ok also, but download and upload speeds on Speakeasy on my computer using the Franklin as a hot spot were in the 3-4 Mbps down, 1-1.5 up, and I wanted to try to improve that. Sometimes I work from home, and needed better, more reliable speeds.We are on the side of a 30-degree slope at about 1,000 feet above sea level, and all the cell towers are west of us with heavy forest and a hill in the way, no doubt contributing to the average coverage. I mounted the outside antenna about twenty feet above ground, fastened to 1 1/4" PVC which is attached to the edge of the roof, and the inside antenna is almost directly below that, so I do not have the recommended twenty five plus feet of separation between antennas. I plan to raise the outside antenna another ten feet or so and will post the results here. Even with that minimal vertical separation (all manufacturers recommend more, or some kind of shielding between antennas) the results were very good. I ran a number of tests, including dB signal strength on the S7 as displayed under settings, about phone, status, and Speakeasy download speed tests on the S7, and on my computer using both the Franklin R910 (Sprint) and the S7 (Verizon) as hot spots.At about fifteen feet from the inside antenna, the S7 showed little gain in signal strength, around 5 dB, but if I moved the phone to within three feet, it showed up to a 25 dB gain, significant, but not very useful if you’re looking for a boost throughout the house. What’s interesting, though, is that the download speeds, tested with the S7, improved dramatically at both fifteen feet and three feet from the inside antenna, almost tripling, 3-3.5 Mbps to 10-11.5 Mbps. These tests were run on Speakeasy using the same server in San Jose, CA. I ran them both in the evening, during peak use, and in the morning with similar positive results. We were not getting dropped calls, so maybe the signal strength shown on the S7 is not as reliable as repeated download speed tests, I don’t know, but obviously I’m pretty happy.I’m an amateur radio operator, and have extensive experience with outside antennas. The Sanqino Home 2G/3G/4G Dual Display Cell Phone Signal Booster is well made, with solid metal construction and coaxial fittings. I would highly recommend trying it if you are having poor cell coverage or want to boost your Internet speeds if using cellular as your access. Be sure to pay attention to the recommended vertical and horizontal separation between the outside and inside antennas. You should also experiment with placement of the inside antenna (mine is in a base cabinet) to see if that improves the strength further away from the inside antenna. I’ve learned over the years that antenna installations require testing and tweaking.

I just installed this yesterday. I am impressed I have installed some Wilson Boosters (now weboost) and never put one in my own home because of the cost. This one performs equally to devices from Weboost that cost as much as 4x more. Since I have only had it for one night I can't talk about its long term reliability but the installation is simple and I didn't have any problems significantly boosting the signal of my sprint air card. I have only been able to get 1-2 bars in one corner of my house and was having dropped connections a few times a week due to low signal. The Sprint air card is now showing full signal in the middle of my house where previously it would not even be able to connect. I am her happy with the performance of this device especially for the price!

We just moved a good way out in the boonies and lost our very good AT&T service coverage. Outside the new house we can maybe get a bar of service and we are not able to make phone calls or even receive text messages. Inside the house just forget it. I did some research and read a lot of reviews. Not wanting to spend alot of money I settled on this cell signal repeater. I was also very skeptical based on user experience that this would even help me at all. To say the least I am very pleasantly surprised that this works great. I did not even install it on the roof yet. I only have the outdoor antenna sitting in a window pointed in the direction of the nearest AT&T antenna and the indoor antenna hung high on an interior wall as far from the outdoor antenna as I can get it. We now get full bars of 4g in all of the house and for a good range outdoors. This exceeded my expectations as far as signal gained. Now it does feel a little on the cheap side as far as the antennas, cables and connectors go. I do have on complaint that might be a pet peave but the use of RF adapters on the cable for the indoor antenna cable. I will probably just replace the cable with a N to N cable and leave the adapters out. Other than that very satisfied. 5 stars.

Well, it was pretty easy to install, except I had to drill a 1 inch hole in the wall to run the cable through. I plugged the hole with expandable foam insulation in a can. And the main cable from the outside to the inside is a tad to short. Now pretty easy to adjust the outside antenna with a helper inside the house to see signal strength. Apparently the only reception we get here is in the 850 MHz band, because I am not boosting any signal in the 1900mhz band, and/or, the booster is defective - no way to tell. While on the roof mounting the antenna I noticed i get one speck of a bar in the 4gLTE band. I don't think its enough to bother boosting. Now, our phones showed we received the 1xCDMA signal at 0-2 bars in the house - it fluxuates. After installing the booster we are getting a constant 4-5 bars on our phones in the 1xCDMA or RTT. So, that's good. I can make phone calls and even get email and facebook. But our data plans are limited so we piggy back off our satellite internet with the WiFi router. When the WiFi is on, our phone still want to use the WiFi to make calls, which really is bad due to the delay of sending signals back and forth to outer space. Ha! It called IWLAN, and apparently Verizon likes it or uses it over out WiFi. So to make good calls I got to turn off the WiFi on the phone. No problem. So all in all, I just need a booster in the 850mhz band, which we are throughout our 900 sq ft home. Good right?

Just installed it, so may be jumping the gun. But this thung boosted my signal from 10% to 100%! I live out in the stix and rely on a hotspot for internet. It runs so much better now! Easy to install.
