FILM ANTENNAS FOR AERODYNAMIC TRUCKS

In a partnership with Freightliner, Hirschmann Car Communication Inc. created a film antenna as part of an efficiency concept to make trucks more environmentally friendly and easier to maintain. The film antenna is integrated in the tractor body, making damage to the system impossible during operation, according to the electronics supplier; currently 20% of trucks’ conventional rod antennas require replacement within a year. The film antenna reportedly offers the best transmission and reception quality for CB radio, AM/FM stations, and weather information radio channels. 

The collaboration between Freightliner and Hirschmann began five years ago with work on Freightliner’s aerodynamically optimized Innovation Truck in 2009. The concept led to the development of the Cascadia Evolution, which launched in January 2013. Vice President of Sales and Marketing for Hirschmann, Oliver Neil said of the partnership, “Large trucks in North America used to have many bulky antennas on the roof, fenders, and mirrors. We now offer a system that enables our customer to develop the aerodynamic design without having to worry about the antennas. It is one of the first innovative components of the concept vehicle that went into series production.
