The zBoost TRIO SOHO Xtreme ZB575X-A boosts AT&T 4G LTE data as well as voice and text for all major carriers.

Enjoy clearer, faster and more reliable service without interruption

If you find that you must be near a window or outside to get adequate cell phone reception, then a zBoost cell phone booster is the solution. There are a number of reasons why you may be experiencing poor reception. The most common reasons are: [ 1 ] Distance from the cell phone tower [ 2 ] Obstructions caused by terrain, trees, buildings [ 3 ] Energy efficient windows and other construction materials

The zBoost TRIO SOHO Xtreme ZB575X-A system includes everything you need

[ 1 ] Step-by-step instructions [ 2 ] External antenna [ 3 ] RG-6 coax cables: 15 and 35 foot cables, and a window-entry cable [ 4 ] Base unit: Amplifies the signal and provides oscillation protection for the carrier network [ 5 ] Indoor antenna: connects to the base unit and repeats the signal to create an indoor cell zone

DIY Setup in 4 steps!

[ 1 ] Mount the external antenna outdoors or in the attic. Take special care aiming the antenna in the direction of best signal for your wireless service provider. [ 2 ] Connect the indoor antenna to the zBoost base unit and place where you need improved coverage. There should be a minimum of 15 vertical feet of separation between the base unit and external antenna. [ 3 ] Connect the two provided RG-6 coax cables (35 feet & 15 feet) using the provided window-entry cable. Use the attached cables to connect the base unit and external antenna through a window, positioning the window-entry cable at the window closing. [ 4 ] Connect the power supply to the zBoost base unit and plug into a power outlet and you are done!

    Impressive I have an iPhone 6 on Verizon. While I get a usable but weak 3G signal at home, LTE coverage is just strong enough that the phone insists on connecting to it, but too weak to actually use data or make calls reliably. If I wanted to make or receive calls, it meant remembering to turn off LTE whenever I was at home and turn it on when I left, which I was never going to remember. Verizon’s Network Extender only provides a 2G/3G signal, so it would have done nothing to solve the problem…

    An Essential Product This unit performs quite well. I would like to say “as advertised” but when you read the specs, what that means is not very clear. In an attempt to keep this review brief, I am going to skip a lot of the gory details.There are multiple vendors for cell boosters and each vendor has multiple units to choose from. Of particular note is the fact that different vendors offer different impedance units. Z-Boost and Wilson, which is now a single company, offer units that are designed for…

    Doesn’t really extend network. This was easy to set up, besides climbing on the roof. So that’s a plus. It does give “better” service when my phone is literally right next to the antenna on the box. Other than that, it doesn’t do jack as far as expanding it through the house. I positioned everything in the most optimal place i could, best signal, facing the nearest tower, adapter near the window, atleast 15 ft from external antenna, etc. It doesn’t extend the network more than a few inches from the device. It stating it…
