Home/Products/Communication Means/PORTABLE RADIO STATION OF THE UHF RANGE R-181-500VU


The radio station R-181-500VU is designed for the exchange of open information and data, secret with the help of external systems of ASD, with data with increased noise immunity and secrecy of work in digital and analog radio networks in the ultrashort wave range. The radio station is intended for installation in mobile objects on the basis of the wheel chassis.
