➊ TECHNICAL PERFORMANCE
• Low loss and high effi ciency
• Azimuth pattern symmetry
➋ DESIGN
• Antennas mounted on a circular ground plane,
fi tted with a standard SATIMO fl ange
• The circular ground plane is made of a lightweight
aluminum foam composite for high structural
strength, low weight and easy handling
➌ REPEATABILITY
• Stiff and robust mechanical design
• Precision machined
• High reliability connectors
