Antenna Elevation and Azimuth Control Systems
Point with Precision. Lock on Target. Stay Connected.
In defense and aerospace communications, antenna positioning systems must deliver pinpoint accuracy in both elevation and azimuth to maintain secure, uninterrupted connections. Whether mounted on aircraft, naval vessels, ground vehicles, or satellite systems, reliable motion control is essential for signal clarity and target tracking.
Helix Linear Technologies supplies high-precision ball screws, lead screws, and linear actuators designed to move antennas smoothly and accurately in all directional planes. Our motion solutions provide the stability and repeatability needed for radar systems, SATCOM terminals, surveillance arrays, and tactical tracking antennas.
Helix components are engineered to withstand the vibration, shock, and environmental extremes common to defense platforms, ensuring mission-critical connectivity in every domain.
Key Benefits:
- Accurate azimuth and elevation control for high-frequency tracking systems
- Low-backlash components ensure stable pointing with minimal drift
- Ruggedized designs for air, land, sea, and space applications
- Scalable solutions for portable, mobile, or fixed antenna systems
Stay locked on target with Helix antenna actuation systems that are built to keep critical communications moving with absolute precision.
