The Indoor Mushroom Head GPS Repeater Kit is a complete solution that enables GPS signal indoors, even in areas where satellite reception is normally impossible—such as garages, workshops, tunnels, basements, industrial halls or large buildings.
With its high-gain mushroom-style GPS/Beidou antenna, 15 m SYV-50-3 premium cable, and a metal-cased 4-stage amplifier with dual filters, this system delivers strong, clear and stable GPS signal coverage throughout the indoor area.
It requires no setup, supports unlimited GPS receivers, and offers up to 15 m indoor coverage (customizable).
Ideal for professional environments, GPS testing, vehicle installations, warehouses, and any location lacking direct GPS satellite visibility.
