The ECOS9-5900DN Series are Elevated Feed Omni-directional antennas with a Mobile Spring Mount and a Direct N termination. They are mobile versions of the ECO Series . They feature a heavy duty spring at the base of the antenna which maintains its vertical position at high speeds but will flex for overhead obstructions.
The antennas are tuned to cover the DSRC frequency range 5800-5925 MHz.
The ECOS are ground-plane independent and can be used on any surface or can be mounted in free space. These antennas have been used in DSRC Truck Platooning trials.
