Radome mounting angle

[Chuck - Raymarine - Moderator]

jrosemeyer,

I would recommend pitching the radome the leading edge of the radome down to match the bow rise angle when operating at planing speeds to maximize range. The radomes have a 25 degree beam angle, 12.5 degrees of which would be located below horizontal. Pitching the angle down another 9 degrees would increase this angle to 21.5 degrees. Determining the minimum height which the radome must be mounted above object located in front of the radome would require knowing the horizontal distance from the highest point of the object in front of the radome to the center of the radome. When provided with this distance, then the minimum mounting height of the radome above the highest point of the object in front of the radome may be calculated using some basic trigonometry (i.e. the tangent function).

Note: The height of the radome's antenna above its base is 5.5".
