The BS421 can be used as Base Stations in bigger networks in areas where moderate traffic capacity is required (up to 7 Erlang). The BS421 is developed to be used, together with the DAMM SB421 Service Box containing the base station controller software, as a platform for small and low cost single stand-alone Tetra Systems.

  • Complete single carrier TETRA Base Station

  • Tower or ground mounted outdoor unit

  • Built-in duplex filter

  • Dual RX diversity on two antennas

  • Can operate on a single antenna (without diversity)

  • Expandable to 4-carrier (four BS421) with jumpers

  • -48V DC operation

  • 10/100Mbit/s ethernet interface (including Voice over IP)

  • Simple, easy and low cost installation

The BS421 Base Station is designed to be mounted at the top of a mast close to the antennas. This eliminates the traditional degradations due to feeder loss and reduces the cost considerably. It is also ideal as a movable Base Station mounted in a truck or on a ship. It is designed for harsh climatic environmental conditions and is fully IP65 sealed.

The BS421 is provided with an internal GPS receiver used for time and frequency synchronisation.
