Description
Overview
The 2225NW precision performance WAAS antenna is specifically designed to meet the demanding standards necessary for worldwide WAAS aviation operations. The 2225NW antenna features both advanced spiral technology and a self-complementary element structure.
The antenna’s low multipath error design has the lowest phase error of all antenna element designs. The spiral minimizes manufacturing errors and its self-complementary currents act to center antenna phase. The large cavity design (1/5 lambda) allows for similar, choke slot-like (radiation pattern), roll off at the horizon and a superior front-to-back ratio.
Features
- Precise and dependable – The low multipath error design has the lowest phase error of all antenna element designs
- Minimizes manufacturing errors – Due to the spiral and the self-complementary currents which act to center antenna phase
- Large cavity design (1/5 lambda) – Allows for similar, choke slot-like (radiation pattern), roll off at the horizon and a superior front-to-back ratio
Applications
- WAAS aviation operations
