The EA7401H anti-icing uses production techniques developed from cellular radio technology to provide excellent RF performance in extreme weather conditions.

Adopting technology from the antenna which is being supplied to the FAA' as part of the ASDE-X program, the 'H' designation depicts the EA7401H's ability to prevent the formation of any ice on the array.

This antenna makes use of 21 heating elements and 2 fans to heat and circulate the air around the inside of the array.

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.
