Description
The TRD1000 Train Antenna is a low-profile antenna that is robust and designed for applications on locomotives, buses, or trucks. The antenna covers the GSM cellular/WiFi and GNSS bands with two separate connectors. It has a high-impact cover that makes it ideal for harsh environments. The antenna is approved for use on 50 kV railway lines.
The antenna has the following specifications: a VSWR of < 2:1 and a nominal gain of 2 dBi for the GSM cellular/WiFi band, and a gain of 26 dBic (relative to an isotropic circularly polarized antenna) for the GNSS band. It has a characteristic impedance of 50 Ohm. It radiates its power equally in all directions perpendicular to its axis in the GSM cellular band. For the GNSS band, the radiation pattern is hemispherical. The antenna also has a rated power of 8 W in the GSM cellular band.
The axial ratio is the ratio between the major and minor axes of the antenna. For this specific antenna in the GNSS band, it is less than 3 dB. This indicates how close the antenna is to a perfectly circularly polarized antenna (axial ratio of 0 dB).
The TRD1000 Train Antenna can withstand wind velocities up to 300 km/h. It is only available in white. It weighs less than 1 kg and has a temperature range of between -30 degrees Celsius and 75 degrees Celsius.
The antenna is right-hand circularly polarized in the GNSS band. This means that the electric wave rotates clockwise in a direction perpendicular to the optical axis. Both transmitting and receiving antennae must have the same polarization so that power losses in the RF system do not occur and to ensure maximum efficiency of the RF system.
The antenna is mounted with 3x M10 studs. The antenna cover is made from ultraviolet-stabilized acrylonitrile butadiene styrene (ABS). The base plate is made of aluminium. The radiator is a printed circuit board (PCB). It is terminated with an N-type female connector for the GSM cellular band and an SMA female connector for the GNSS band.
