A-133 GPS Active Antenna
Introduction
A-133 Active GPS Antenna is an active GPS antenna without housing, aluminum base and a power protection circuit built-in to protect the active Low Noise Amplifier (LNA), and the host GPS receiver at the connector end from the danger of shorting. (Note: GPS receiver front-ends can be destroyed or de-graded by external antennas over-loading or shorting). The A-133 Active GPS Antenna is a low profile GPS active antenna for multi-purpose GPS mobile antenna for customers looking to integrate into their own product. The antenna is designed for standard power input voltages ranging from 3V~6V with reverse polarity shutdown, over-current sense shutdown and EMC power line suppression. And, like all the other ARKNAV antennas, A-133 Active GPS Antenna is made with high quality double-shielding cable and silver coated conducting pin, and meets RoHS directives.
Features
A-133 GPS Active Antenna is the only innovating design antenna with performance,
quality and a Power protection circuit built-in to protect the active LNA’s, and most
importantly the host GPS receiver down the connector end from the danger of a
SHORT circuit external antenna (Note: GPS receiver front-end can be destroyed or
de-graded by an external GPS antenna in an over-load or short conditions. The
A-133 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 A-133 antenna is also design as a standard power
input voltages in range from +3Vdc to +6Vdc with reverse polarity shutdown,
over-current sense shutdown and an EMC power line suppression. The most
important over-all design concept of the A-133 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.
