Wi-Ex ZBoost 510

This cell phone booster will increase your signal strength by one or two bars. If your home or office has dismal cell phone coverage, as mine does, this booster can make a difference. Often a spot outside your building, or on top of your building will have better coverage. This device picks up the signal from a small stick-like antenna and relays it via a cable to a book-size station where you want the signal. Using this in my studio I can now get two bars where before I had none. The zBoost is the least expensive signal repeater I could find.
