The zBoost YX030-35W is an additional 35" of RG-6 Coax with F Connectors. Extend the run length between the Signal Antenna and the Base Unit with the lowest loss RG6 cable available (9dB/100ft @ PCS 1900MHz). Also includes a 2250MHz mating adapter to connect two cables together. Our cable is tested to 3000MHz and uses ULTRA grade connectors. We only recommend extending your cable length if it allows you to locate the Signal Antenna in a location with better reception. When using over 60 feet of cable, we recommend upgrading to a stronger Signal Antenna to prevent signal degradation.
