Product Content Description:

GA38 is the integration of a high performance GPS patch
antenna and a state-of-the-art low noise amplifier into a
very low profile/extremely compact/fully waterproof
enclosure which, when connected to a GPS receiver with
2.5 ~ 5.5 V DC antenna power, provides excellent signal
amplification and out-band filtering & rejection, it can
provide 3 V or 5 V input voltage.
Features:
1. Compact construction/low profile
2. Fully weatherproof
3. Magnet and screw mount base
4. Excellent temperature stability
5. Low noise figure
6. High sensitivity
Applications:
1. AVL
2. Fleet management systems
3. Car navigation
4. Weather balloon
5. Security surveillance
6. External antenna for handheld GPS
