Product introduction
Application
Four-star full-frequency four-arm helical antenna
SSY3701B
The antenna adopts a four-arm spiral structure with a relatively
stable phase center, which reduces the influence of the antenna on
the measurement error;
The antenna gain is high, the beam pattern is wide, and the
effect of receiving low elevation signals is good, ensuring that the
antenna can receive the satellite in different attitudes;
The antenna is equipped with a high-band out-of-band
suppression low-noise amplifier circuit, which can effectively resist
external electromagnetic interference, and has low power
consumption to ensure the endurance of the device;
The antenna is small in size and light in weight, and is suitable
for use on various devices that require antenna weight, such as
drones and various handheld terminals.
This antenna is a Samsung seven-band four-arm helical antenna covering GPS L1 / L2, BDS B1 / B2 /
B3, GLONASS L1 / L2,Galileo E1/E5. It has the characteristics of small size and light weight. It is widely
used in navigation scheduling, tracking monitoring, measurement and control And other fields. Based on the
four-arm helical antenna's low requirements for antenna attitude, it is especially suitable for many
applications such as drone, such as aerial photography, traffic monitoring, remote telemetry, etc., and can
also be applied to various handheld terminals, high-precision positioning modules, etc. .
