Better performance Broadband Radar Above illustrates that raising the Broadband scanner off the hard top allowing most of the radar energy to clear the hard top. Best performance Broadband Radar 850 mm Hard Top Width For best performance, the radar should be positioned to allow the beams to clear the superstructure of the boat. Below is a guide to determine scanner height in relation to a vessels hard top overall width. Optimum Performance Elevation of scanner 0.85 m 1.0 m 1.2 m 1.4 m 1.6 m 1.8 m 2.0 m 2.2 m 2.4 m 2.6 m 2.8 m 3.0 m Hard top total width Direct Mount 70 mm 115 mm 163 mm 210 mm 255 mm 303 mm 350 mm 395 mm 443 mm 490 mm 535 mm Every Increase of 400 mm of hard top width over 1.0 m wide: Increase height by 140 mm. 12.5° 25° Elevation of scanner Better Performance 2.8 m 3.2 m 2.4 m 2.0 m 1.4 m Hard top total width Direct Mount 67 mm 112 mm 157 mm 202 mm Every increase of 400 mm of hard top width over 2.0 m wide: Increase height by 45 mm.
