The angle of the radar beam you are searching for is called vertical lobe angle. On this radar (this antenna) it's 12.5 degrees on each side of the horisontal plane. That means that if you didn't have this tilting mekanism, the radar would have poorer performance when looking sideways and the boat is heeling more than 12 degrees. Next step in this magnificent design is to automatically calculate the heeling angle, max and min, over some time, and then position the antenna in the mean angle between these angles. When it goes out more than 5 degrees from calculated angle it makes another calculation and adjustment. It's maybe possible to achieve the heeling angle from the heading sensor, usually attitude sensors (pitch, roll and yaw, static and dynamic) are included in these sensors.
Good to see another video from you, I guess you play when your Captain’s away😉. Please post a follow-up video when you’ve had a chance to evaluate the usefulness of your tilt mechanism. I completely understand your need to choose the road less traveled in your designs but I’m not sure how valuable this would be at sea.
Thank you! I ran some FEM analysis on it and with wind up to 50 knots it still had a good safety margin. It’s a quiet light weight build compared to many of the stainless steel versions out there
Great video, love your workshop and thanks for sharing, very innovative! I am about to do a design up on CAD to have cut and welded by someone else, sadly I don’t have your great workshop :-( It has been a year now, have you decided with using it in that time if the tilt was a worthwhile thing to include?
Thanks! We actually sold the boat by the end of the season. We have a video explaining why, long story!. Anyway, I still think the tilting is worth having. Since you have to make a lot of other parts, adding the tilt function is not that much extra work . It of course depends of what kind of sailing you do, but if you feel that having a nice radar setup gives you more confidence and safety onboard, go for it:)
@@jacobkollerup thanks so much for your reply and yes I agree, it’s easy enough to include and a worthwhile addition for the benefits. We will be live aboard’s, doing a lot of sailing, great to have this simple addition
Thanks! So almost all parts are custom made fra raw stock. The tube is a 60mm diameter aluminum tube. All the brackets are from 10mm aluminum plates and some 6mm L-shaped profiles. The actuator is from Amazon, think the brand is called windynation
@@jacobkollerup I demand perfection. :) But in all seriousness, great job! Fun project. I'm doing a linear actuated helm panel - talk about overkill....
