    19.3" 49 cm 9" (22.9 cm) 19.3" (49 cm) Radar Concerns The TracVision antenna must be kept out of line with nearby radars, as their energy levels may overload the antenna’s front- end circuits. In an ideal installation, the antenna is mounted four feet (1.2 m) above and four feet (1.2 m) away from the radar (measured from the center of the antenna dome to the center of the radar).
