So far so good

Item just arrived today, but quickly installed it with the outdoor antenna sitting in a window, and the results are immediate and significant. We have a metal building for an office, and it sits in a very low lying area. If we want to use a cellphone we must walk out front. Placed the antenna in the front window and set the indoor amplified antenna just 20' away and we have boosted signal by 3-4 bars for everyone's cell phones. AT&T, VZ and Sprint users alike.

We bought this to boost our cell and data signals at our place in Northern Wisconsin. We were told we were in an ATT 'dead zone' but could get 4G and sometimes LTE outside. We have a mobile home, so signals were almost nothing inside. After installing, we get LTE and 3 bars everywhere inside. I had to construct a PVC pole to get it 15ft high, but the small antenna and bracket hardware made it easy to attach. I used different sized PVC that I could telescope to get high enough, and when attached together and to bracketed to the trailer, it is very sturdy. Set up was easy...once plugged in it did everything automatically. VERY HAPPY. Now we can cancel our expensive landline.

zBoost - TRIO SOHO Cell Phone Signal Booster
Posted by: GadgetsandTools from: on
I am using this at my cabin, it seems to work a little better than my old one, not exactly 2500 sq ft coverage as advertised. I may need to move the unit & antenna around later to get a better signal.
The antenna and the base unit need to be as far apart from each other as possible, ideally, straight up on the roof as high at you possibly can to get the best signal.

Works as described

We have 1 or less bars of signal in our house without this booster. With it, we can not only do texts, but actual talking and sending pictures. I am happy I took the chance.

I installed this in my metal shop and now I get better reception inside the shop than I do outside.

great for our cell phone signal
Posted by: saltminer from: on
works really good, now we can use our phones in the house. We have ATT for our carrier, we now get three and four bars. Before we got this we had to be by a window to use them, now we use them any place.

Bought this for a home in a rural area with sketchy coverage. It gets the job done
