Detail Information

Description :

The Trimble compatible is a low profile GPS active antenna system for the next generation multi-purpose GPS mobile antenna products for Telematics, Fleet Management, Navigations 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 L1 band small signal carrier that originates from the 24 orbiting USA satellites located thousands of miles over-head and with the ground reception power sensitivity at over -130dB. The Trimble compatible antenna is also design as a standard 3 Vdcpower input voltages with reverse polarity shutdown, over-current sense shutdown and an EMC power line suppression.
