Innovative
New Design GPS Antenna
|
Active-3 GPS 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 Active-3 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- 1antenna
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 Active-3
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 .
