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:

- Distance from the cell phone tower

- Obstructions caused by terrain, trees, buildings

- Energy efficient windows and other construction materials in your building

Setup in 4 easy steps!

zBoost External Antenna

zBoost cables

zBoost power supply

1. Mount the External Antenna

Choose a location for the External Antenna using your cell phone to determine the area of strongest signal. The coverage your zBoost booster provides is largely determined by the strength of signal received by the External Antenna.

2. Place the Base Unit and Indoor Antenna

Mount the Indoor Antenna on a wall facing the direction where increased coverage is desired. The zBoost Xtreme performs best when there are no obstructions between the Indoor Antenna and your mobile device. Connect the Indoor Panel Antenna to the Base Unit using the supplied 15 feet of RG-6 cable.

3. Connect the External Antenna and Base Unit using the provided cable

Connect the two 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

Great product and very easy to install.
Stephen C. Barresi
I located the antenna as directed in my attic, window, outside, inside then, just about everywhere trying to get a better signal to no avail.
This product is not worth anything it did not work at all....buy the Wilson stuff it is MUCH better .

This review ran a bit longer than I expected, so let me sum it up by saying that this zBoost SOHO YX545 did exactly what I needed it to. It boosts the signal quality in my house from at most 2 bars to a solid 5 and didn't require any complicated setup or configuration. It isn't often that a plug-and-play device like this truly beats out all expectations!

The main thing to keep in mind during the install is that the external antenna and base station need to be seperated as much as possible. The reason for this is that they both use the same frequencies for communication, and having them close together will cause feedback. When the zBoost detects feedback, it turns down its internal antenna strength; which can seriously impact the range you will get from the zBoost.

Now, on to the details:

I live in a 2 story, 3000 square foot house with a radiant barrier installed in the attic. The radiant barrier is great for keeping utility costs down, but it wreaks havoc on the cell signal in the house. Because of that, I'm lucky to get 1 or 2 bars inside, with constant missed and dropped calls, even though the signal quality outside is just fine.

For the last 3 years I've been working from home and using an AT&T cell phone as my primary work number. This has led me to try all types of methods to boost my cell signal, and I'm often forced to take work calls in the yard since it's the only place where my phone works.

Last week I discovered the zBoost SOHO YX545 and decided to give it a try. One of the first things I noticed after unpacking it was that the 50' extension cable seemed extremely thin and poorly insulated compared to a standard coax/RG6 cable. I decided I'd use it anyway, so I headed up to the roof to find a place with a good cell signal.

Size Name: Up to 750 sq. ft. Verified Purchase
I live in an area that is about equidistant between cell towers. My best signal strength in the house is 2 bars or less. I lost calls all the time, sometimes just because I pivoted while talking and placed my head between the phone and the tower. The lower level of the house is partially sub-grade and I can never rely on maintaining a connection.

This extender has solved all the above problems. I have a clear conversation now, but no increase in cell strength (still 2 bars), When I turned it on, the phone showed no bars and thought I was too close to the repeater, but reception was clear. Routine contacts have commented that my voice is not choppy as it was before. I can definitely recommend this product's signal boosting capacity.

INSTALLATION: Windows on 2 sides of the house showed the same cell strength. I chose one that was the easiest to string cable along the wall and placed the transmitter as close to mid-house as possible. I placed the antenna as high in the window as possible. Do clean the window before mounting the antenna. It took less than 10 minutes to unpack and install. The hardest part was unraveling the coaxial cable. Instructions are short and clear. The trouble shooting table consists mainly of being certain to have more than 8 feet between the antenna and the transmitter, otherwise they interfere with each other.

I'm writing this review partially because it is therapeutic but mostly to help others in my situation buy the right product for the job! Short story for those who don't want to read my novel... Wilson rocks ... Z-Boost not so much. If you're on the fringe of coverage, do yourself a favor and spend the extra 50 bucks for a superior quality product (Wilson Dual Band Pro). You won't be disappointed!

The Z-boost (or what I like to call the Z-bust) was to be used at a cottage on the fringe of cellular coverage (1 bar standing on my roof and barely any 3G coverage). I purchased the z-boost along with the YX510 panel antennas thinking I had what I needed. I was pretty excited about finally getting 3G signal at the cottage!

I spent a few hours hooking up the system (with no help from the lousy instructions). I had GPS coordinates of the nearest cell towers and exact directional info on where to point my antennas. I started with 100 ft of RG6 cable to give me some flexibility on locating the antenna and booster as I was aware of the challenges resulting from proximity oscillation between the two.

Once installed, I powered up the iphone to see the results... The z-boost showed all systems go (with the very informative green light). From 10 feet away, I had negligible improvement in voice or data. Once I moved outside the 10 foot range, nothing at all.

I masked my disappointment and climbed back on the roof and adjusted the antennas to the next closest tower (I had exact directional info for this one too). I climbed back down and repeated the testing process...no better. At this point, I was ready to throw everything back in the box but read the little slip in the box that said, "do not return this product...call z-boost installation support".

Size Name: Up to 750 sq. ft.
Pros: Easy to set up. No vertical seperation requirements. increased signal strength for voice and data. Customer support is excellent. relatively small base. Grey color blends into background. quality workmanship/appears sturdy

Cons: signal degrades rapidly after about 5 ft. comes with a short length of cable. Coverage area is greatly overhyped.

Summary: I like the product and will keep it for my office. I sit about 30 ft from window in a cubicle maze. I was able to place the antenna in the window and put the base in my cube for great signal. Only real issue I have is that the device only has a range of about 5-6 feet before I lose 3G. Signal drops off completely after about 18ft which is about 972sf coverage area. However, the fabric covered partitions between the cubes erode the signal much quicker. Therefore coverage is hit or miss when I am on the other side of the partition wall. I called customer their support/technical support folks to validate the actual range and it was refreshing to here they were quite forthcoming with the true range of 15-20 ft. I think this is an ideal product for small open areas. Not so much for large areas or walled areas. I would increase the star rating if the device would provide more coverage and if the advertising was more factual about actual coverage area.
