The magnetic mounting system makes it perfect for rental vehicles, borrowed trucks, or situations where you rotate between multiple rigs without tools or expertise. Compatible with Astro, Astro 220, and Alpha units, it integrates directly into your existing Garmin ecosystem. For extended range tracking and reliable real-time positioning, this remote antenna transforms your mobile command center's situational awareness and operational reliability in the field.
