[ 1 ] Step-by-step instructions [ 2 ] External Antenna [ 3 ] 50 feet of coax cable (RG-6) [ 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.

Easy Setup in 4 easy steps!

[ 1 ] Mount the External Antenna where you have the strongest cell phone signal, typically on a roof or in an attic. [ 2 ] Connect the indoor antenna to the zBoost Base Unit and place where you need improved signal. There should be a minimum of 15 vertical feet of separation between the Base Unit and External Antenna. [ 3 ] Run the RG-6 coax cable (50 feet) between the Base Unit and External Antenna. [ 4 ] Connect the power supply to the zBoost Base Unit and plug into a power outlet and you are done!

I had an older zBoost (YX510-PCS-CEL) along with the supporting directional outside antenna. It worked great with my old Motorola non-smart phone and old 3G carrier. When I changed to an iPhone and changed carriers to AT&T, it completely stopped working. If you disable Wi-Fi and (in Cellular) disable LTE, your iPhone will tell you exactly what type signal it is getting. Even way out in the country, mine was all 4G. Without the zBoost, I only get 1 bar in the house and often "no service". Outside is 1 or 2 bars but who wants to have to go outside every time a call is needed. So I bit the bullet and bought the new ZB575-A for AT&T 4G. Here's what I found: With the base unit connected to my old 3G directional antenna (which zBoost Technical Support told me would not work), I had a standby 5 bars!! But when I placed a call, it dropped down to 1 bar. Still an improvement over no boost but a little disappointing. I swapped out the old antenna (outside on the house eave) for the new uni-directional stick antenna (came with the unit). Now I have 3-4 bars standby and 3-4 bars when making a call. As much as you can be "happy" over a "thing", I'm happy! Thanks to zBoost for great Technical Support...

Two more notes. If your cell phone signal is only 4G, you apparently must have one of the newer zBoost 4G products to work. Also, according to zBoost, the number of bars you have in standby when in the vicinity of a zBoost product is not an indication of phone signal strength; it is being affected by background noise from the zBoost. You must be making a call for the signal strength meter to give an actual value.

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.

This booster isn't cheap, but so far, I'm very impressed. My installation was far from ideal. I live in a small apartment on the 2nd floor of a tall building. Installing it in a strong-signal location like the roof was not an option – the best I could do was to stick it outside directly above my kitchen window (I ended up using mounting tape to hold it to the side of the building, since drilling holes in the outside walls is not something we're allowed to do.) The signal from that location was not particularly strong to start with.

Other fun things about my setup:
- I had to buy a flat window cable and a second spool of coaxial to snake the cord through my kitchen window. More interconnections, more signal degradation.
- I ended up using exactly 65 feet of cable - the maximum allowable length for RG-6 according to the instructions.
- The instructions repeatedly insist that you need at least 15 feet of vertical distance between the base station and the outside antenna. I can’t have had more than about 10 feet vertical (although about 30 feet horizontally.)

In other words, it would not have surprised me at all if the booster did nothing, given all the caveats of my installation. However, so far it seems to be working great.

Just moved and could not even talk on our phones much less use the internet. Live in a valley in a rural area. Put the antenna on the roof on a 6 foot pole. I now have flawless phone conversations and good internet. Went from "Internet not available" to 3 bars of 4g. We have 2 story house and put the receiver on the second floor middle of the house (square shaped 1k square feet per floor).
We seem to get a strong signal everywhere except on the outside porch. Even there it is usable, just slower and still good phone calls.

All in all, I was worked about the price at first, but could not be happier. Only bad thing was getting on the roof and running the coax cable through the attic in July. In retrospect, should have paid someone. Just get the antenna as high as possible.

We live in the country, we don't have a land line, therefore, our cell phones are paramount....the ZB575X-A gives us 3-5 bars of signal strength throughout the house, much better than one bar to "no service"! I can send photos while talking on the phone and people don't complain they can't hear or understand me due to poor signal/service. The system was very simple to install is very easy to operate.

I was skeptical about paying this much money for something I wasn't sure how well would work. I work out of a home office and would have calls dropped on verizion often. Well, it got to be a problem so I purchased this and loosly hooked it up with the antena just upstairs. Not much gain, so the following day I placed it a the peak of my roof, followed the directions to the letter and now I get a 100% signal, all bars on downstairs. I have a large house and placed the receiver close to get ceiling nead my desk, but I get 1-2 bars more even upstairs. Before I install the booster I would get 1-3 bars inconsistantly. This really does work and it increased my reception more than what I had standing on my roof looking at the phones meter.I use an app called ReceptionMe that shows a meter, it is 100%, I kid you not.
