A-INFO Antenna Brackets (mounting brackets and positioning kits) are precision-machined mechanical mounting systems designed by A-INFO Inc. to securely hold, align, and position RF, microwave, and millimeter-wave antennas (such as horn antennas and log-periodic antennas) in laboratory, testing chamber, and outdoor field environments.
​Key Features & Mechanical Design
​ₒ High Structural Rigidity & Precision: Constructed from high-strength anodized aluminum alloy or stainless steel to prevent mechanical flexing and maintain precise antenna alignment under vibration or wind loads.
ₒ ​Multi-Axis Adjustment: Offers adjustable pan (azimuth), tilt (elevation), and polarization rotation (horizontal/vertical), allowing engineers to align antenna boresights in anechoic chambers with high precision.
ₒ ​Low-Reflection / Non-Metallic Options: Selected mounting brackets utilize low-dielectric non-metallic materials (such as Delrin/POM) to minimize electromagnetic scattering and interference during EMC/EMI antenna testing. ​
ₒ Universal Standard Mounts: Features standard 1/4″-20 and 3/8″-16 tripod threads, along with customized flange mounts compatible with standard antenna tripods, mast poles, and automated positioners.
​Primary Applications
4. ​EMC/EMI Anechoic Chambers: Mounting horn and log-periodic antennas onto antenna masts and turntable positioners for radiated emission and immunity testing.
2. ​Antenna Range & Field Testing: Securing reference and test antennas onto tripods or field masts during gain calibration and radiation pattern measurements. ​
3. Satellite & Radar Installations: Fixed mounting of horn feeds and small directional antennas on towers and communication platforms.
