OGGG-BD-33-V is a four-system total frequency point vehicle antenna supporting GPS, BDS, GLONASS, and GALILEO, which can be widely used in automated farm equipment, high precision UAV, vehicle, and other industries, especially for many applications of high precision mechanical farm equipment, such as high precision tractors, planters, cultivators and harvesters, etc. Its passive antenna has high gain, wide beam, good reception of low elevation angle signal, and can still receive stars generally in the more severe environment of blocking; and the passive antenna works in a wide frequency band, which can well support multi-system multi-frequency point work, such as L5, B3, LBand other frequency points, which significantly improves the system stability; and small volume, lightweight, reliable structure, protection level up to IP68, which dramatically enhances the machine whole machine The reliability of the entire device, such as waterproof, vibration, etc.; Finally, the out-of-band antenna suppression is high, which can effectively avoid the signal interference from communication base stations and other signal instability.
