Features: Wide frequency rangings: the antenna can work between 1300MHz and 10GHz, covering a wide frequency rangings. Log-periodic characteristics: Log-periodic antenna have Log-periodic characteristics, which mean that its gained varies with the changing of frequency. gained: the antenna gained rangings from 6 to 9dB, with highly gained. Communication system: Log-periodic antenna is commonly used in mobiles communication system, such as cellphone, base stations and so on. Due to its wide frequency rangings and highly gained, it can provide better communication quality and coverage. Log-periodic antenna also used in scientific research field, such as earth observation, etc. Specifications: Material:ABS Log Periodic Directional Antenna 1300MHz-10GHz Directional gained: 6-9dBi VSWR: <1.5 Impedance: 50Ω Type:Standard Version,Upgrades Version Package Includes: 1Set UWB Antenna note: Please allow 1mm errors due to manual measurement.
