Broadband radio relay station R-300
Broadband radio relay station R-300 is designed to provide digital radio relay communication in stationary and field communication systems for military and civil purposes.
The product allows you to create long-range radio channels with a bandwidth of up to 16 Mbit / s and a range of up to 30 kilometers for one interval.
The station provides integration into the local area network of the facility using the Ethernet data transmission interface.
Main components of the R-300:
– Transceiver unit – is the main element of the product and performs all signal conversion processes for information transmission. It provides routing, switching, modulation and demodulation functions for radio signals.
– PoE injector – designed to transmit 48 V DC from the power supply to the transceiver unit over the Ethernet data line.
– Directional dipole antenna.
– Power Supply.
Antenna AD-22 / B manufactured by Trival Antene is connected to the transceiver unit and is designed to emit and receive radio signals at an operating frequency. It can also be used as part of an antenna array consisting of two antennas and is connected to the transceiver unit using the CA-300 antenna matcher. As part of the antenna array, the gain increases by 3 dB.
The antenna is a directional log-periodic dipole antenna and covers the frequency range from 225 to 512 MHz.
