Do I need to purchase an antenna to use my Rocket hub?

The Rocket™ hub hardware comes with internal and/or external antennas included and as a guideline to areas of usage, please check for our detailed coverage maps. In some cases, depending on your location, building structure, and other factors, you may wish to add a supplementary antenna that is mounted outside of your building location to enhance your wireless signal strength. The Rocket hub is compatible for use with a supplementary dual-band 850 MHz/1900 MHz cellular antenna. These antennas may be known as “3G antennas”, “HSPA antennas” or “high gain antennas” and may be found at a variety of electronics and electronic parts retailers. Please check with your desired retailer as to antenna availability and pricing to suit your needs.
