Description

In production

The Siderion 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.
