The TRD Iridium Train Antenna is a low-profile antenna that is robust and designed for applications on locomotives, buses, or trucks. The antenna covers the iridium band with one connector. It has a high-impact cover that makes it ideal for harsh environments.
The antenna has the following specifications: an operating frequency of 1616 MHz to 1626 MHz, a VSWR of < 2:1, and a nominal gain of 3 dBic (relative to an isotropic circularly polarized antenna). It has a characteristic impedance of 50 Ohm. It radiates its power equally in all directions perpendicular to its axis. The antenna also has a rated power of 10 W.
The axial ratio is the ratio between the major and minor axis of the antenna and is less than 3 dB for this specific antenna. It indicates how close the antenna is to a perfectly circularly polarized antenna (axial ratio of 0 dB).
The TRD Iridium Train Antenna can withstand wind velocities up to 300 km/h. The antenna is only available in the color 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, 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 4x M4 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.
