So what is a boat cell phone signal booster? Essentially it is quite similar to a microphone, amplifier and speaker systems that are commonly used to amplify the sound of a person’s voice in larger places. A signal booster uses an outside antenna on the boat to get the weak outside cell signal then sends it by means of a cable to a signal amplifier, and finally passes it to an inside antenna. The latter broadcasts the stronger signal to a larger area in the boat cabin. Worth noting is that the system works in the opposite direction to which means that you can be sure of both receiving and making calls and data requests with a quality signal. However, keep in mind that a signal booster doesn’t make a signal itself rather it amplifies the already existing weak signal so make sure there is some outside signal or faraway carrier tower.Read More
