Description
Overview
The SA1800 3D GNSS choke ring antenna from Stonex has a unique design that ensures an excellent multipath reduction performance across all GNSS frequency bands including L-Band. Due to its sub-millimeter phase center stability, it is ideal for applications such as CORS stations, bridge and building deformation monitoring or geological monitoring.
The ability to receive low elevation signals with high gain and wide beam width makes SA1800 an excellent choice for tracking visible satellites while also providing stable and precise GNSS data in complex environments, such as obstructed environment of tree lines or construction.
The antenna LNA features an excellent out-of-band rejection performance, which can suppress the EMI, providing stable and reliable GNSS signals. The Stonex SA1800 antenna effectively avoids disconnections when receivers are being interfered with by wireless communication systems, for example power grid, communication base station or radio modem applications.
The Stoenx SA1800 is well suited for use as a GNSS reference station. It has a cover made of Glass Fiber Reinforced Polymer (GFRP) material which makes it strong and durable while also protecting the inside antennas from dust and water.
