Product Description

Product Description

GRA440-LS GNSS antenna is a high reliable indoor transmitting and receiving antenna with anti-seismic, dustproof and waterproof rating IP69K. The frequency range covers the full-band satellites, such as BDS, GPS, GLONASS and GALILEO, which can satisfy the signal transmitting and receiving of the BDS system and the indoor coverage of GNSS signal.

Common Application: Transmitter antenna for indoor coverage of GNSS signals.

Specialized Applications: GNSS BeiDou short message indoor space applications for tunnels, mining trucks, fortifications, firefighting, and specialized vehicles

Product Features:

GRA440-LS is made of ABS+PC material, sturdy and reliable structure, as well as waterproof and breathable process with patented design, which makes the protection level up to IP69K, which can protect it from dust, ultraviolet rays and water, and ensure the antenna work reliably for a long time.
