➊ TECHNICAL PERFORMANCE
• Avoid any additional alignment procedures
when aperture is changed
• Minimize interaction between probe
and the antenna under test
➋ DESIGN
• Apertures integrated with a wideband dual
polarized orthomode junction
• Tapered ends to minimize diffraction effects
• Lightweight for easy handling
• Easily interchangeable apertures
➌ REPEATABILITY
• Repeatable radiation performance due to the
axial symmetry of the interchangeable apertures
• Stiff and robust mechanical design
• Standard SATIMO circular interface for precision
centering
• Precision machined
• High precision PC 3.5 mm Female connectors
• Precision pin for accurate polarization alignment
