The EA7401M is the latest offering from Easat and uses production techniques developed from cellular radio technology to provide excellent RF performance.
Adopting technology from the antenna which is being supplied to the FAA as part of the ASDE-X program, the 'M' designation depicts the EA7401M's ability to operate with single, dual or dual diversity magnetron based transceiver systems.
The antenna offers sub 0.33° azimuth 3dB beamwidth giving excellent range and azimuth resolution and provides operation with 40ns pulse width without pulse distortion. The antenna also offers zero squint with frequency, making it particularly suitable for use with frequency agile and frequency diverse systems.
Offering a high standard specification, the antenna includes circular polarisation for weather penetration and inverse cosec2 beam shaping to minimise effects of rain clutter. Additionally, coverage down to -40° below the horizon, low weight and low noise make the EA7401M ideal for mounting on top of Visual Control Rooms.
