The COD4-4552 unity gain broadband dipole antenna is designed to cover the entire 450-520 MHz frequency band. Suitable applications include low power base stations and RF Control Stations in the emerging whole-of-government UHF frequency allocations, and other applications requiring a wide operating frequency bandwidth. A unique circuit board radiator design provides a balanced and effective centre fed dipole radiator. As a centre fed antenna, not only is gain consistent across its entire frequency band but the vertical radiation pattern is stable in beam width, resulting in consistent performance across the entire frequency band. This antenna is internally DC grounded for optimum lightning protection and for the reduction of static noise, and is lightweight for easy installation on support structures.
