Stonex SA1500 2D Choke Ring GNSS Antenna


The SA1500 2D choke ring GNSS antenna from Stonex 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.



The Stonex SA1500 2D choke ring GNSS antenna has a unique design which ensures an excellent multipath reduction performance across all GNSS frequency bands including L-Band. Due to its submillimeter 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 SA1500 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 SA1500 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.
