Not all GNSS receivers can handle very strong signals from high-gain antennas. If the signal entering the receiver is too strong, it can be outside the receiver’s recommended input range.
The Septentrio mosaic-H used in our simpleRTK3B Heading board has a specific input signal range for its GNSS antenna inputs. This means that when you connect a high-gain antenna, especially with a short antenna cable, the signal reaching the Mosaic-H can be stronger than the receiver is designed to handle.
Our GNSS Signal Attenuator solves this by reducing the antenna signal by a controlled amount before it reaches the receiver.
