Swegeo HA20
Superior Satellite Tracking & Stable Phase Center
It fits into any application that requires a small size and lightweight antenna without sacrificing high performance in high-precision positioning, particularly in UAV, pocket-size RTK, handheld/tablet, or other portable system applications.
Reduces The Sources of Measurement Errors
Multi-arm spiral technology ensures high performance on right-hand circular polarization and phase center stability. It further lowers the measurement errors.
Compact & High-Performance Device
The overall design provides a high gain on low-elevation satellite signal reception so that a higher number of satellites are available for position calculation.
Performs Exceptionally Well
Built-in low-noise amplifier, two-stage filter, good out-of-band suppression strong anti-interference ability provide fully reliable antenna performance in harsh electromagnetic environments.
It is small in size, lightweight, and easy to carry and install.
