A-131 is a performance GPS antenna with power and RF signal protection built-in to protect the active low noise amplifier (LNA) and the host GPS receiver at the connector end from danger of shorting, (GPS receiver front-ends can be destroyed or de-graded by external antennas over-loading or shorting). The RF signal protection shield on the bottom cuts out noise and provides a more accurate signal.
A-131 is designed for multi-purpose integration applications such as GPS tracking products, etc. The antenna is designed for standard power input voltages ranging from 3 V ~ 6 V with reverse polarity shutdown, over-current sense shutdown and EMC power line suppression. And, like all the other arknav antennas, A-131 is made with high quality double-shielding cable and silver coated conducting pin, and meets RoHS directives.
