Review on Powerful Cell Phone Signal Booster for Home and Office - Enhance GSM, 3G, and 4G LTE Voice and Data Signals Across All Major Networks - Covers up to 5,500 Square Feet by Jim Bethea

This signal booster is phenomenal! We have used high quality branded units in a few other ranch buildings and on a good day they can provide the same signal boost as this unit. Thought I'd try a cheaper brand and it was worth it. Installation took about two hours. This involves making a 12 foot pole that attaches to the top of the roof. (One good tip we found that works really well: find the nearest cell tower for your carrier on one of the many cell tower finder websites, pinpoint it on Google Earth, use a measuring tool, and draw a straight line from it Your building (this will give you the exact line of the location the outdoor antenna should be pointing at.) Directions are easy. Can't say enough good things about this block. We don't have service at the ranch and after installing this amp we have 3 bars indoors and we can stream movies. To put it mildly, we are very satisfied.
