Product overview
The ComNav AT360 Geodetic Antenna supports multi-constellation, multi-frequency GNSS reception for land survey, agriculture, construction and deformation monitoring systems. Its signal coverage includes GPS, GLONASS, BeiDou, Galileo, QZSS, IRNSS, SBAS and L-Band. A low-noise amplifier and high gain support signal reception and satellite tracking at low elevation angles. LNA gain is 40dB ± 2dB, with a noise figure of ≤ 2dB. The antenna uses RHCP polarization and provides 5.5dBi gain at zenith, with a phase center offset of ± 2mm.
The AT360 measures Φ147×67.7 mm, weighs ≤ 500g and features a TNC female connector. Its IP67 waterproof and dustproof design supports outdoor use, with an operating temperature range of -40°C to +85°C and a storage temperature range of -55°C to +85°C. Humidity tolerance is 95% under non-condensing conditions. The antenna operates from 3.3 - 15 VDC and draws ≤ 45mA. Electrical specifications include 50Ω nominal impedance, output VSWR of ≤ 2.0 and passband ripple of ± 2dB.
