Cell Phone Booster for Home, Up to 6,000 Sq Ft, Smart LCD Display, Built-in Indoor Antenna, Boost 5G 4G LTE for All U.S. Carriers - Verizon AT&T T-Mobile, FCC Approved

I am a technical expert (but you don't need to be.)== Problem ==We stayed at an RV campground with very weak T-Mobile service (1 bar). My iPhone 14 would drop calls, and I could not check emails, etc. I also attempted to use my T-Mobile Home Internet device unsuccessfully (1 bar = weak signal.)== Solution ==Out of desperation, I purchased this cell phone booster. I mounted the antenna on a 15-foot "flagpole" mast attached to the back of my RV. Ultimately, I obtained excellent (4 to 5 bar signal), and I could download at 70 Mbps (Speedtest.net). The booster fixed my "dropped call" issue, AND the internet was fast enough to stream movies from Netflix, YouTube TV, Vudu, and more (using the T-Mobile Home Internet.)== Caveats ==* The booster has 5 "repeaters", each with a digital display showing signal strength and diagnostic information. My installation indicated 2 of the repeaters were overloaded, and the system automatically turned those two repeaters off. A nearby Verizon cell tower caused this. Therefore, I could not use those two channels (but they were unnecessary for my T-Mobile connection.)* Of the remaining three repeaters, 2 indicated "low isolation" and "Osc" for oscillation. A good analogy is the feedback "squeal" you hear when a microphone is placed too close to a speaker. I had the antenna (which is highly directional and analogous to a flashlight) mounted on the back of the RV and the repeater unit located on the desk about 10 feet below. I moved the antenna to the front of the RV (now the desk was about 25 feet BEHIND the antenna), and the low isolation / OSC indication went away.* You can manually turn each repeater on and off. I experimented and discovered that turning off one of the repeaters resulted in a 10X increase in speed. Essentially, I was forcing the T-Mobile devices to use the "higher frequency" bands associated with 5G. In fact, I would see 5G UC on my iPhone.== Summary ==This device worked extremely well. It provided us with high-speed internet connectivity and solid cellular service. Just remember, the antenna is highly directional and must be aimed AWAY from the indoor transceiver (repeaters). In addition, you may need to experiment to maximize performance. Each time you move the antenna, you must "power cycle" the repeater unit. You may also need to power cycle (or cycle airplane mode) whenever configuring the repeater channels.

Seems like easy directions.I think the product is quality for the price

I'm using this unit to improve Verizon (Visible) and AT&T. Verizon shows SOS inside, 1 maybe 2 bars outside. AT&T is sometimes 2 bars inside and 4 bars on my roof, but still not very usable inside. The cable is 60 feet long, and the power cord is only 5 feet. The single cable length is perfect for the single booster box. The power cord is very limiting on locating the large booster box. I'll need a light extension cord.My brick ranch building is below the horizon in the shadow of a bluff, 2 miles from the cell tower. Both companies (on the same tower) shoot signals more down the highway perpendicular to my location, not toward my location. And there's a Verizon repeater 1 mile in a different direction that's mucking with the signal. So I'm mounting my antenna pointed toward that biggest multi company tower and mounting it as high up as practical. Not on a roof corner, but on the gable at the highest near the ridge for the additional height. I'll use a 3 foot J pole there to get the antenna above and away from the shingles. For now, the antenna is mounted on a step ladder.My first trial with the antenna aimed and the box sitting high up against the wall wasn't good. I got OSC on two channels. I moved the booster and re-aimed the antenna and the signal got barely usable. Not great but improved. Turns out I had some interference because I had the booster too far forward with respect to the antenna, causing some signal overlap. I moved the booster about 8 feet away facing farther from, and sort of "behind" the direction the antenna was pointing. WOW! I get 5g on AT&T about 30 Mbps and upwards of 10 Mbps on Verizon sitting at my desk! I was hoping for more, but those numbers are very usable.It took a lot of experimenting with locating the booster box, but it was worth it. I was about to give up and send the unit back. The install isn't fully finished and I have about 3 hours of work into it so far. It's not hard, but it isn't fun, either. I had to step through blown insulation in the attic where the roof is very low with lots of nails. There's no walkway up there, and stepping low between and on the rafters is challenging. Locating the coax from below was challenging too. I ended up poking a straightened coat hanger up through the coax hole in the ceiling so I could find the coax that I pushed up from the booster location in the living area ( it coiled up under the insulation). I drilled one hole through the gable large enough for the coax to go through. I'll seal it later from the elements.I used Cellmapper to confirm the tower and Google Earth to locate the cell tower and point the antenna. It was easy to "draw" a line on the satellite image from my roof to the tower and get a really good idea where to point the antenna.All in all, a pretty decent booster package and not a real tough DIY project. Would a different brand booster with a phone app to help install the system have been a better choice? Maybe, for the $150 or so extra, it might have saved me an hour or more. But still, locating the booster indoors to eliminate interference and bring the db numbers up was the hardest part. The good news is that this booster works well. And although the booster box is pretty fricken big, there's only one box to deal with, which I also like.

I needed a booster very badly. And this booster fit the bill. It is very easy to set up and works great. So if you are looking for a cell phone booster this is it.

This device kept me from dealing with cable companies for internet! I live in a rual area where we can only get coaxial cable internet service. Before installing this my phone had 1 bar of service. Now I'm 4 bars and 4G. It also works for my Verizon internet. Installation is straight forward. Put the antenna in a high position facing towers. Run the cable and put the module in a position to best serve signal needs. Please don't be intimidated by some of the other reviews saying you need professional Installation.

Hard to set up

Went from 1 to 2 bars up to full signal and also up my data speed. I know it works with Verizon well and T-Mobile. Even boosted my Verizon mifi to full signal.

Went from 1/2 - 1 bar to 5. Just point it at the tower. No need for WiFi calling anymore. Will update if anything changes. Very easy install just be careful on roof.
