Title: It Really Worked!!!
Review: The booster was easy to install and it did just what it said it would do. I have AT&T and live in a tiny home that has an all metal exterior. My cell reception was terrible and this device boosted me to 3-4 bars of 5G.

Title: Ineffective for me
Review: I live in a low spot and don’t get a very good cellular signal. Most times 1 bar, randomly 2 bars oitside of my house. Needless to say my reception is poor. I installed this booster, aimed the antenna and checked my ability to do anything with my cell phone. I had to be within 6 feet of the booster to see any difference in actual signal but I still could not do anything with my phone. It seems that this setup would work if the building you are in is the cause of your poor reception, however, if you have a poor signal outside to begin with then you will just have a poor signal coming from the booster. And yes, I did monitor the signal strength when aligning the antenna to the nearest cell tower.

Title: Works as intended
Review: I only had 1 bar outside my house, and spotty reception inside the house. After installation, the signal inside the house went from spotty/1bar to 3bars of cell service. The coverage inside the house depends on how many walls with wiring are in the path of the signal. From the farthest point in the house away from the internal antenna, I am still getting 1-2 bars of signal.

Title: Great Value Excellent Results
Review: First of all, be certain to find out which band your connected to at the location where you will be using this booster. Fortunately, this particular unit covers most bands. Secondly locate the direction that the tower is from your location. If you follow these steps and this booster is for your band, all you need to do is install it an point it toward the tower. This unit automatically adjusts the gain eliminating steps that are required with other boosters.The main reason I needed this booster is that the construction of my home blocked cell service. I did my research and after installing this booster, I went from barely one bar of 4G to three bars of 5G.

Title: It works well for me
Review: I live in a120 square foot, cement with 1/4 inch steel mesh imbeded, with 5 foot of soil on 3 sides, geodetic dome. I would receive -115dB of 4G signal if I put the phone against my only window.. Outside, my signal strength is around -105db to-110dB for 4 and 5G. My results: averaging-90dB all 5g. The system works. The antenna is 35 feet from dome antenna and 8 foot above ground.

Review: Pros:Boosts Multiple Bands: This cell phone signal booster is capable of boosting a wide range of bands (66/4/2/25/5/12/17/13), making it compatible with major U.S. carriers like Verizon, AT&T, and T-Mobile. It has improved both 4G LTE and 5G signals, resulting in better call quality and faster data speeds.Good for Small Spaces: The coverage area of up to 1,500 sq ft is perfect for a small home, office, or apartment. It effectively eliminates dead zones and improves signal strength, which is great for people who struggle with reception indoors.FCC Approved: The booster is FCC approved, which means it meets all the necessary safety and performance standards for use in the U.S. It gives me peace of mind knowing it’s compliant with regulations.Easy to Set Up: The installation process is straightforward. The instructions were easy to follow, and all necessary components were included. It took me about an hour to set up, and the result was worth the effort.Improved Call Reliability: Before using this booster, dropped calls were common in certain parts of my home. Since installing it, call reliability has greatly improved, which is a major advantage for maintaining clear and uninterrupted communication.Cons:Requires Proper Placement: The external antenna needs to be placed correctly to get the best signal. Finding the ideal spot took some trial and error, which was time-consuming. A signal strength meter or more detailed guidance would have made this easier.Limited Coverage: The 1,500 sq ft coverage area may not be sufficient for larger homes or spaces with multiple levels. It works well for a small home or individual rooms, but you might need multiple units for bigger areas.Price Point: The price is a bit steep for the coverage area provided. While the performance is good, it would be better value if it offered more coverage or if additional features were included.Bottom Line: This cell phone signal booster is an effective solution for improving reception in small spaces, providing better call quality and faster data for major U.S. carriers. Proper placement is key to maximizing its effectiveness, and while the price might be high for the coverage, it delivers consistent performance, making it a worthwhile investment for those needing better indoor reception.

Review: Working in the film business, my projects take me to different locations every day. Sometimes there is cel phone coverage, and sometimes there isn’t. As a freelancer who is always looking for my next job, answering calls and texts promptly can be the difference between being employed or not.I was very happy to find this unique style of cell phone signal booster. Others cell phone boosters I have used come with 2 huge antennas connected to an electronic box by 20 to 50 feet of cable. They work for a permanent installation, but are simply not portable.The great thing about this booster is that there is only one smallish external antenna which connects to a control box the size and shape of a wifi router. I was able to mount the entire setup into a small pelican case that I can open up on location, move it around until all the lights show a signal, and just like magic everyone’s cel phones work!Another advantage of this system is that the antenna connects to the base using an RG6 cable – the exact same that you use to hook up cable TV – so they are readily available in all different lengths. It also operates at 12 volts, so it is very easy to adapt it to operate from a car lighter socket or (in my case) a movie camera battery!

Review: Yes, just like my headline says, this signal booster did indeed provide a very noticeable improvement in mobile phone signal strength, but it too some effort.Firstly, this signal booster provides all the necessary bits and pieces for installation, with a generous amount of coaxial cable. The instruction manual is really good and you definitely should study it to get optimal results.Basic installation and setup is pretty straightforward following the manual. But it’s the fine-tuning that really makes all the difference. Following the guidance of the instructions produced the results.Since installation at my friend’s rural property, this booster has been very reliable. We mounted it on an existing antenna mast. The big difference in performance was basically trial-and-error to find the optimal direction to point the antenna.The nice part of that is that you only have to put the work in once. All in all it took us about 3-4 hours of not terribly hard work and fiddling about. Now mobile phone signals come in nice and clear. I would subjectively say on a scale of 1 to 10, the signal went from about a 2 to a 6 or 7. Pretty impressive.Overall, we found this a quality signal booster and definitely worth the price.

Review: The SIGNALBRICK brand cell phone signal booster can be a valuable asset for homes and businesses that present extra challenges for adequate cell phone signal support. Examples include large and extra-large structures, locations in valleys or other geographical challenges, structures with large amounts of steel content, etc.This reviewer has first-hand (and expensive) experience with substandard cell phone reception here at the tree farm home base. Even though we are located on relatively flat and high ground approximately 30 minutes-drive from the signal policy controlling folks at the mighty CRTC offices in downtown Ottawa, the most common signal reading is between zero and 2 bars, with many calls and texts that are unsuccessful.We ruled out installing a land line during initial construction 5 years ago due to both the high cost of linking the quarter-mile distance between the structure and the main grid connection at the road, plus the minimum monthly charge of approximately $50 to maintain a land line residential number.The first step was to set up a 60 foot tall tower with a receptive mini dish. The next challenge was to get the signal properly distributed in and around the main building, an all steel construction Quonset hut. This involved the installation of additional cabling and in line signal boosters.The signal was still not reliable and a secondary booster was added to the receptor dish on the 60 foot tall antenna tower. An interior signal booster system was also installed. The most recent acquisition is another booster system for the recent addition of a large 3 season screened outdoor room.Still searching for the holy grail of decent and dependable cell service, we recently acquired the present product under review. The tech specs are not that impressive and the 1500 square-foot coverage is only approximately half the single floor square footage of the present structure. There are competing peer products on the Amazon website offering 5000 ft.² coverage in a similar price range.This booster is both FCC and IC certified. Despite all of the descriptive print focused on major U.S. mobile carriers, it is also properly configured to receive all of the current band width signals used by all of the major Canadian wireless carriers. All of the relevant troubleshooting and signal status system LED indicators are built-in for ease of day-to-day operations.The maximum signal boost gain is unknown at this point. Any boost incurred will also increase the amount of time required between battery charges as the phones do not have to work as hard in terms of signal finding power needs.We are currently waiting for the installation technician to install this system and look forward to updating this review if there are any significant changes to report at that time.Conclusion:The SIGNALBRICK brand cell phone signal booster can be a valuable asset for homes that present extra challenges for adequate cell phone signal support. An overall neutral product score of 3/5 is assigned accordingly.

Review: I have a slight dead spot for cellular reception right where my house is located. I’m able to call without issues on my main floor but not at all in the basement. This Cell Phone booster has increased my cell reception and works excellent. I used an existing stack that was previously mounted on the peak of my house for an older antenna I don’t use anymore. I mounted the outside directional antenna to this post and did my best to point it directly at the closest Bell tower. I ran the cable down to the basement and placed the booster on a table. I included a picture to show the green lights. I seem to be getting a strong signal boost for the 700MHz, 850MHz, and the 1900MHz frequencies. I am getting nothing for the 2100MHz frequency. I’m using Public Mobile which uses the Telus/Bell network. With the booster, I’m getting a constant range of reception from -100 dBm to -85 dBm. This is OK to good according to the Signal App. My phone though shows 4 bars most of the time. Overall, I’m pleased with the increased reception. The booster works and the improved signal is noticeable. Excellent product!
