ATT Mobile Phone Signal Booster Mingcoll 700MHz Band 12/17 Cell Signal Booster 4G LTE Repeater Amplifier with Outdoor Directional for Home and Office (White-XK7)

I recently purchased this to solve my signal issues, I had another booster that I thought had gone bad, so I removed it my signal went from week to non-existent. We had 2 spots (literally 2 chairs) that would get and maintain a signal to have a conversation. within my house.So I decided I needed to get another booster, and chose this after some research and reviews.I downloaded a signal app on my phone, and began researching the areas outside the house that were strongest, already knowing the tower was to my NE, I started near one of our only signal spots, and moved toward the tower. I found a sweet spot along the back of the house, just outside our pool cage.I mounted the antenna, and ran the line (I need to get an extension, as the provided line is about 15' too short to reach where I would really like to put the box. So it is temporarily strapped to one of the trusses in the attic.) and then ran the indoor antenna to the general area I wan to place it.Being that the box is currently in a temporary location, I did not mount the indoor antenna inside yet, it is also strapped to a truss in the attic.Surprisingly, that seems to work fine,so I may permanently mount the indoor antenna in the attic, saving putting holes in the drywall to run the line.Immediately I went from 0-1 bar service to 3-4 bars throughout most of my house.I cannot stress how important it is that the exterior and interior antennas need to be spaced apart a minimum of 20-25 feet, any less has a affect on the effectiveness of the booster.

So I did my homework, made sure I ordered the correct Yagi for my cell signal, and downloaded Network Cell Info Lite (free app). But I half expected this thing to be a disappointment. So when I unboxed it today I was careful to keep everything in case of a return. But that won't be necessary.Sitting at my bar in my new constructed house my S7 Edge usually has zero bars. As I type this review it now has 2-3 bars of LTE. Very impressed with this product, it works great to bring what ever you can pick up outside to the inside.But again, do your homework, read instructions, and get the app I listed above or something similar. Yagi needs to be pointed at the nearest cell tower, the app showed me I was wrong on this. Yagi off, cell signal in house is -121, Yagi on cell signal in house is -91.Later on this year I'll put one on my shop.

My cell phone service at my house was poor. I had to go outside to make a call. I could send a text from inside but if I wanted to send a picture I was out of luck inside or outside. I wanted a cell phone based security system, but that was not possible. I decided to try this Verizon 4G signal booster. I put the outside antenna on the ridge of the house about 6 feet above the roof pointing at the cell tower. I ran the cable into the attic and toward the other end of the house. When I got to the end of the longest cable I installed the repeater and the other cable and continued away from the antenna toward the other end of the house. When I came to the end of the second cable I installed the indoor antenna on the end and laid it on the insulation in the attic facing down toward the room below. I powered up the repeater and got green lights. I decided to test it out at this point and see if it improved my cell service before doing anything else. I can now make calls from inside the house and send pictures. I am not going to change a thing. I have only had it working for a couple of hours but my first impression is good.

YOU MUST DO SOME RESEARCH BEFORE PICKING WHICH MODEL TO BUY!! That being said I was able to find out which frequencies my local towers were on and their locations (antennasearch,com or other searches). Without that information, this booster will be useless to you and you'll probably get on the Amazon to write up a very frustrated 1-star review. Mine went from no service in my basement to full bars with 4G in the Utah mountains. My nearest tower is about 6 miles away and kind of hidden behind a small knoll, this booster only works if you have line of sight to the tower or very close to it.

As described, works well. Boosted my indoor house signal from 1 bar to 3 bars. Outside on roof top I can get 1 to 2 bars. Easy set up. Helps if you have a second person to monitor indoor reception as you align the antenna to the tower (especially when you can't see the tower because of hills or trees).

We tried others and sent them back...this one is the bomb. Three bars at all times now! We have a new metal roof and no signal, so we bought a booster not believing it would work after many failures. This one worked immediately, thank you so much. Half the price of the others too!
