RF2050 mobile multiband transceiver with increased resistance against radio-electronic warfare is intended for installation in all tracked and wheeled vehicles. It is fully compatible with RF20 and RF23 transceivers. Depending on the selected frequency band, the transceiver communicates with older RF13 and RF1301 transceivers. You may use two types of modems on frequency hopping channels - P2P and NET to transfer data. On fixed frequency channels you can use the NET modem complying with MIL-STD-188-220, which is compatible with MD13.1 modems or with modems in ZV13.1 amplifiers. The transceiver design allows easy upgrading of existing vehicle installations.

The transceiver is manufactured in two versions: 2310.100.10 without the co-site filter and 2310.100.11 with the co-site filter.

The co-site filter allows simultaneous operation of multiple RF2050 transceivers or of one RF2050 transceiver with RX2050 receivers in one vehicle in 30 MHz to 90 MHz operating band. There must be at least 1.5 m between the recommended types of vehicle antennas and spacing between receiving and transmitting frequencies of at least 10 % to guarantee compatible operation.

The RF2050 transceiver can also be remotely controlled over PRC20 protocol, which allows the transceiver implementation in the AR20 automatic rebroadcast station and connecting of the RC20 remote control.
