Title: Excellent Results!!
Review: I purchased this Cell Phone Repeater on Amazon. My package came with an aerial antenna, cable from the aerial antenna to the amplifier, the amplifier, cable from the amplifier to the indoor directional antenna, and the directional antenna. It included mounting hardware.Based upon weather conditions I have historically had intermittent cell service at my home, so was forced to keep a landline as an emergency backup. Additionally, I am remodeling and am putting radiant barrier on the ceiling, outside walls, and in the floor throughout the entire house. I expected this to make my bad reception much worse. Hence, I thought I would see if a repeater would truly help. After a little research, I purchased this model.I needed to locate the amplifier in the center of the house, so I felt the indoor directional antenna would not be as beneficial, since my office is located “behind” the antenna. I contacted the company and they immediately sent out a omni-directional antenna at no cost. I could not be happier!I used OpenSignal (an app on Play Store to find the direction of the cell tower my device attaches to when at home). It is easy to use and shows an arrow pointing towards the tower that is accessed. I installed the aerial antenna on a 30′ tower I put up and pointed the antenna towards the cell tower shown on the OpenSignal app. Be sure to drive an 8′ ground rod and attach the rod to your tower. I used #4 multi-strand copper wire.I routed the cable from the aerial antenna to the location in my house where I would place the amplifier. I used zip ties to secure the cable to one leg of the tower. The outdoor aerial antenna needs to be 25 feet vertically or 32 feet horizontally from the indoor antenna.The signal strength on my Galaxy s24 Ultra before turning on the amplifier was -117dBm to -121dBm (which is poor). I have AT&T/FirstNet. The phone registered 2 bars of 4G signal, which is as good as it ever gets at home. I plugged in the amp and immediately the signal strength improved to -79 dBm and the phone screen registered 5 bars of 5G service!!!It is an unbelievably incredible system. I will purchase this same repeater if this one is damaged by lightning.The only negative is that the attachment of the aluminum antenna to the aluminum mounting plate is with two aluminum rivets. One rivet failed during preparations to mount it so I drilled out both rivets and mounted the antenna to the bracket with two panhead screws/washers/lock washers/nuts. I did not want a heavy wind to break it loose from the bracket.

Title: Very nice!
Review: We live in a very remote section of the ozark mountains in north central Arkansas. We do have some cell towers around but my house area has very poor service. When we moved into a mobile home with a metal roof, we lost everything. Our internet tower is tmobile and was not picking up in the window and we were about to cancel our internet due to it. Our cell phones did not work inside either. And the land line got more expensive by the day.We decided to try a cell booster in hopes we could use our cell phones and internet inside the house, and disconnect the land line.If your reading this review you may be overwhelmed like I was, at all the options on Amazon. I had no idea which product to even try.I took a gamble and ordered this one.Omg I could not be happier!!! The antanea went up easily and with the use of the locator app, I easily found the closest cell tower. I only had a weak signal so I had my doubts if it would even lock on. But I put it up and tightend it all down. I installed the components in the house and it was the easiest thing ever!!! I just located it as directed in the manual and plugged it all in. The unit done the rest and immediately had a hard lock on the signal. It not only brought nearly full signal to our cell phones but also took my internet tower up to a strong signal as well!!! Now we can not only text on our phones but make phone calls without dropping! We can also stream movies from any room in the house. Even during bad storms, she holds signal unbelievably long! I’ll lose my internet some times if the storm is bad enough. But I normally keep enough bars on my phone to watch weather alerts. It will however go out if you lose power. But kicks back in as soon as the power comes back on.I highly recommend this booster!!! Between the price, the ease of installation and the efficiency at which it works….it’s a very good investment !!!

Title: It Works!
Review: This unit works very well and was simple to setup, but thats because I was replacing an existing unit and already had a pole to mount the outdoor antennae. The tricky thing with these boosters is being able to get the outdoor antennae high enough and pointed in the right direction and still having enough cable to get the indoor antennae in the right position for covering your home but not where it interferes with the outdoor antennae. They should be at least 32 ft. apart and further is better. They only give you just enough cable to accomplish this so this can be problematic depending on the layout of your home. My outdoor antennae is mounted on a 12 ft. pole and the indoor antennae is on the floor in the basement broadcasting up through the house. One thing that bothers me is the fact that the cable that comes with it has propietary type connectors so if the cable goes bad I dont know if its possible to find a replacement cable. All in all it is worth the money but dont expect 5000 sq. ft. of coverage. Maybe 1/3 of that on a good day.
