The GA-88H is the integration of the high performance GPS patch antenna and a state-of-the-art low noise amplifier into a fully water resistance enclosure. When connected to a GPS receiver with +3 to +5.0 VDC antenna power, it can provide excellent signal amplification and out of band filtering & rejection for that receiver. The antenna can be fixed by an optional mounting base.
