Description

The SA233 is an affordable and highly efficient multi-band GNSS helical active antenna. The device allows concurrent reception of GPS /GLONASS /BeiDou & Galileo signals to improve signal availability. The minimum 2dBi peak gain is amplified using a 39dB LNA gain to ensure the best signal quality in any situation. The SMA male connector together with the rubber joint sealing make them reliable, robust and waterproof.
