VHF Radio Repeater

SEE Telecom designs and manufactures VHF repeater systems
(BDA – Bi-Directional Amplifiers):
  • To enhance the radio coverage of public safety networks ;
  • To extend the coverage of private radio networks in major infrastructures like airports, shopping centers, hospitals, confined areas such as tunnels, metros, underground car parks, offshore platforms, underground mines, etc...

Built-in waterproof wall-mounted rack, the VHF radio repeater can be installed in the harshest environment, indoors or outdoors.
The VHF radio repeater can be ordered with different frequencies, powers, with different power supply voltages, with or without battery backup, and with a GSM modem. SEE Telecom proposes a complete portfolio of solutions with off-air and optical repeaters, advanced technologies as band selective, channel selective, AGC per time slot, squelch, frequency shifting, WDM, remote monitoring HTTP-SNMP for each installation.

The VHF repeater has three RF connectors, one connected to the antenna pointing toward the base station, and the second one is connected to the antenna or radiating cable in a tunnel or building. The operational monitoring and control can be performed via SNMP, SCADA, via Ethernet using a web browser installed on a PC, which gives access to the GUI, or remotely via an optional LTE modem which allows accessing the repeaters GUI from everywhere, using the 4G network and the third connector. This interface contains an easy-to-use configuration page. The SC-DIRRAC also has a sum alarm output that can be connected to an external alarm system.
