The TQ-230W is an outdoor yagi antenna that can be aimed in the direction of the closest cellular tower and pick up signals up to 30 miles away. The wide band yagi antenna is designed to cover 2G/3G/4G/and WLAN systems for Cellular, PCS, AWS and LTE frequencies. When installing, any metallic rods must be at least 3 feet from the antenna. Mount the entire assembly to a 1 to 2 inch diameter pole (not included). In addition to the antenna, mounting equipment is included for mounting to either a flat horizontal surface or wall. For best results, the white fiber-glass portion of the antenna should be mounted above the roof line and unobstructed in the direction of the tower.
