Base Radio Station

The Tersus RS05B radio station is a base radio solution for wireless applications. It provides reliable data communications for mission-critical applications where a combination of stability, superior performance and long range are required.
The RS05B provides high speed, high power, wireless data links and has been designed to survive the rigors of GNSS/RTK surveying and precise positioning applications. Up to 35W transmit power maximizes range and supports operation in difficult urban areas. The RS05B is equipped with a LED display and a keypad which is used for checking the operating status, changing the operating channel, and transmitting power level.
