Underwater Antenna Shallow Antenna

Product Overview： Our Shallow Underwater Antenna is professionally engineered for nearshore, river, lake and shallow-sea underwater positioning & wireless communication, perfectly solving unstable signal and corrosion failure troubles of ordinary marine antennas in brackish water & shallow turbulent waters. Optimized anti-multipath interference design eliminates shallow-water wave reflection signal loss, enabling stable continuous GNSS lock when vehicles surface or partially submerge within rated depth. Adopted marine-grade anticorrosion housing and fully sealed IP68 structure, it withstands long-term submersion, seawater splash, tide immersion and high-pressure washing, serving marine research, underwater robot, aquaculture monitoring, hydrological mapping and underwater engineering positioning reliably.

Application field： ROV, AUV, USV unmanned underwater vehicle navigation River, lake and coastal hydrographic survey & bathymetry mapping Marine monitoring buoy & aquaculture underwater data collection Shallow water salvage, diver tracking and offshore construction
