GNSS Antenna U-GGB13S

Short Description:

Features 1. Using multi feed point design to ensure the superposition of phase center and geometrical center which could minimize the influence of measurement error to lowest range. 2. High gain of the antenna element and the direction map beam width to make sure the receiving satellites performance of low elevation mask. 3. Resistance multipath effects board inside could reduce the measurement error caused by multipath. 4. Water proof, shock proof and lightning resistance. Application Survey...
