A Mobile Phone Signal Booster works by capturing an existing signal with an external antenna and amplifying it using a booster, then rebroadcasting it with an internal antenna. It’s an effective way to boost weak signals in the building. Enjoy better signal strengths and data speeds without looking for a connection.
Install the external antenna on the exterior of your boat where it can get the best reception, usually the roof of the boat. Install the Booster in a protected location and connect with the provided cables to your antenna. Don’t forget to test your product to be sure everything is working as it should. Important: if you’re travelling frequently, you should purchase and install a 360-degree pipe antenna to catch signals from all angles.
A mobile signal booster can improve the strength and reliability of your signal when you’re out on the water. This is especially important in areas where signal can be weak, and you need to stay in contact and connected to the internet while you’re out exploring.
