The N201 cavity penetration dimensions are a mere 4.75 inches long by 3.75 inches wide and less than 1 inch deep (excluding connectors). Typical flange dimensions are 6.5 inches long by 5.5 inches wide.
The antenna assembly is a four-element antenna aperture. It is designed to receive righthand circularly polarized (RHCP) radiated signals from NAVSTAR GPS satellites and couple the radio frequency signal to the antenna electronics (supplied by others) via four coaxial cables. The four-element array is used to adaptively steer nulls in the presence of interfering jamming signals. The antenna assembly contains the antenna elements, radome, housing and SMA female connectors. This technology can be used for platforms such as missiles and other expendables, unmanned aerial systems, helicopters and land vehicles.
