The Bird AT-500 is a portable RF test instrument designed for analyzing antenna performance in mobile and base station applications. It provides a cost-effective and graphical method for determining antenna quality by measuring key parameters such as VSWR, Return Loss, Match Efficiency, and Reflection Coefficient (Rho). Its rugged, hand-held design and extended battery life make it suitable for field use. The device supports single frequency readings and frequency sweeps for comprehensive testing and optimization.
