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
Do you have any blind spots from the sails, rigging, mast or boom being in front of the radar? I ask because I am debating whether to do pole mount or mast mount. Mast mount would be easiest for me, but I know I will probably have a 20-degree blind spot straight aft because of mast just behind radar.
Haven’t noticed any blind spots. My theory is that the boat is constantly changing the course slightly. So any objects “hiding” in the blind spot will be visible for the radar a few seconds later.
@@jacobkollerup I demand perfection. :) But in all seriousness, great job! Fun project. I'm doing a linear actuated helm panel - talk about overkill....

Very good idea, that is easy to be done with SignalK and Openplotter

Wonderful engineering and installation. Will consider this idea in the future when I’m ready to install a radar. Thumbs up on the job and video!
Excellent work! This gives me sound ideas on how I will construct mine.
Nice video! I got the same B&G V9 unit and the same dilemma: where to put the radar when I get one.
Very nice solution, my only doubt is the
stabilisation of the pole using only the sea railing.

Clever concept and I like it very much. I am curious on the supplier of the actuator and how it is holding up so far.
Thanks! The actuator is from Amazon, think the brand is called Windynation. Probably not the best, but so far it’s holding up very nicely:)

Perfect done
Thank you so much 🙏🏻
Very good work.
Could you share links to the parts you used? (Pole, linear actuator, brackets, etc…)
That could be very useful!
Ciao!

@@jacobkollerup Do you recall the thickness and type of the aluminum tube? It seems there are lots of options.

Just checked, it’s Ø60mm, wall thickness 3 mm. Hope it helps
@@jacobkollerup Thanks I ordered that size in 6061-T5
What, no IMU control? :)
I know, I’m slacking off 😆
