Enhance your cellular signal within your business, home, vehicle or boat. With over 35 years of experience, ATG will walk you through the process of selecting the best cell booster for your property. We offer commercial grade cell boosters and have successfully boosted signals in many areas. Our test equipment allows us to determine signals in 700, 800, 1900 and 2100 MHz spectrum bands. A cell booster detects available signals indoors and outdoors. We measure bands, channels and frequencies before we deploy each system.
