GPS ANTENNAS
GPS Antenna
-02
Stingray GPS antenna is the only innovating design
antenna with performance, quality and an RF protection circuit built-in to
protect the active LNA¡¦s, and most importantly the host GPS
receiver down the connector end from the danger level of high power RF CW
source exceeding over 1watt. The Stingray 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 Stingray antenna is also design as a standard power input
voltages in range from +2.5Vdc to +12Vdc with reverse polarity shutdown,
over-current sense shutdown and an EMC power line suppression. The most
important over-all design concept of the Stingray active antenna is the
complete protections of the host sensitive GPS receiver made from any
manufacturer that it serve and can also be destroy or de-grade using an
improper design antenna.
