Freightliner moving antenna inside the truck
Hirschmann Car Communication has developed a film antenna system, which Freightliner says it will unveil on its next generation of trucks in North America.
Hirschmann and Freightliner began collaboration in 2009 with the development of a truck prototype known as The Innovation Truck – the concept which led to the development of the Cascadia Evolution, which was launched in January of this year.
“It is one of the first innovative components of the concept vehicle that went into series production,” Oliver Neil, vice president of sales and marketing at Hirschmann Car Communication, says of the antenna system.
Integrated in the body of the tractor (in space between the structural body panels and the interior lining of the cab), the flexible antenna system is reported to limit operational damage, while also improving aerodynamics of the trucks.
The system requires no external components but Hirschmann says it achieves the best transmission and reception quality for CB radio and reception of AM, FM and weather information radio channels.
Traditionally, North American trucks a fitted with large roof antennas, but studies suggest that upwards of 20 percent of these have to be replaced within a year.
“With its Innovation Truck concept vehicle, Freightliner is moving in the direction of trucks with optimal aerodynamics – from redesigned fairings and underbody panels to reduction of external components such as exposed exhaust pipes or radio antennas,” Neil says.
