The pistola is a low profile combine antenna system for the next generation multi-purpose mobile antenna products for telemetry, fleet management, navigation's and AVL applications. This small print size of the antenna design does not reflect over-all performance, since the antenna itself needs no ground plane aid to deliver the cellular frequency and L1 band small signal carrier that originates from the 24 orbiting USA satellites located thousands of miles over-head. The active GPS antenna is also design as a standard power input voltages range from +2.5Vdc to +12Vdc with reverse polarity shutdown, over-current sense shutdown and an EMC power line suppression.
