Coverage Area 

With all Cell Phone Signal Boosters, the actual area that you can cover inside is directly related to how strong the signal is where you mount the outside antenna combined with the strength of the amplifier. With a very strong 5 bar signal outside where you mount the external antenna, it's possible to achieve nearly 10,000 sq ft of coverage. However, if you only have one bar of signal outside, your inside coverage will be limited to one room. Actual coverage area is affected by many factors and is difficult to predict, so when it doubt, give us a call to discuss your situation.
