SATEL Proof-R4+

SATEL Proof-R4+ is a heavy-duty receiver only radio modem that meets the requirements of machine control and smart farming and marine applications. It is built to last dirt, vibration, sand, dust, liquids and lightning. It is a flexible and cost-effective solution that has profound electrical protection; both the power and data lines as well as the antenna interface are surge protected. It also has additional filtering on GNSS frequencies.

SATEL Proof-R4+ consists of an IP69K sealed housing and a receiver only radio module with wide 70 MHz tuning range for frequencies 403 … 473 MHz.

The SATEL Proof-R4+ receiver radio modem is compatible with SATEL-EASy+ / -TR4+ / SATELLINE-EASy / -TR1 based radio modems as well as several other radio protocols.
