Transport antennas from KATHREIN-Werke KG

The issue of ensuring stable radio communication in transport has always been and remains an urgent task in the design and operation of rolling stock. This is due primarily to the fact that vehicles are highly mobile, high-speed, performing the strategic tasks of mass passenger and cargo transportation. As a result, increased requirements are imposed on them both in terms of reliability and operational safety.
Taking into account this approach, numerous companies that design and manufacture component radio equipment for rolling stock, their main goal of creation is the production of high-tech equipment with the best performance characteristics, capable of operating under conditions of increased influence of electromagnetic fields of electrical contact networks, a high level of mechanical vibrations and technical pollution.
Based on advanced achievements in the field of radio communications, as well as the availability and use of modern technological materials, the German company KATHREIN-Werke KG has developed and successfully implements a number of special antennas and antenna-feeder equipment designed specifically for transport operation.
The operating frequency range of this equipment ranges from 68 MHz to 2,7 GHz, i.e., it covers both radio frequency channels of technological radio communications and channels of mobile operators (800, 1800-1900, 2000 MHz).
Taking into account the harsh influence of the environment, the housings of transport antennas are made of modern radio-transparent composite materials, externally coated with a coating highly resistant to mechanical stress and dirt sticking, have an aerodynamic streamlined shape, highly aesthetic ergonomic design.

Antennas of complex design, which have so far been widely used in transport, are being replaced by minimized antennas with better radio engineering and mechanical characteristics. Such antennas are resistant to mechanical damage, icing, pollution. They have significantly reduced weight and size indicators, while maintaining high radio performance.
Ukraine already has experience in using this type of KATHREIN antennas. Antennas of a certain type work successfully, providing reliable radio communication for the rolling stock of the mining and processing plants in Krivoy Rog. These are the so-called technological "turntables" - locomotives with 8-10 cargo platforms.
As you know, the operating conditions of equipment in this industry are considered difficult - ore dust, crushed stone ingress during loading and unloading operations. And also one of the main factors that influenced the transition from the previously used loop antennas to KATHREIN transport antennas was the fact that the branches of trees growing near the railway track constantly deformed and even destroyed the antennas. With the use of Kathrein transport antennas, the situation has improved significantly.
