Possible performance loss 50% of beam power 50% of beam power Above illustrates an installation with the Halo Radar mounted directly on to a large hard top. This installation could suffer decreased performance as the radar energy is either reflected or absorbed by the hard top. ¼ Note: Where the mounting surface is constructed of any form of metal you must elevate the dome so that the beam has complete clearance, else performance will be severely impaired. Good performance 12.5° 11° The image above illustrates that raising the radar scanner off the hard top allows most of the radar energy to clear the hard top.
