I drew up my boat & the console I have; to test 3 things. 1st where the radar can see its full potential, 2nd where the radar's R.F. waves might impact someone in the boat for extended periods of time (i.e. standing at the stern and fishing). and lastly where would the radar hit the water.

tested flush: Attachment 67586
tested at 3" mount height: Attachment 67587

I'm going to contact Garmin to confirm that the readings occur at center of the dome's height, but I'll will do a mount height shorter than 3" because I have some tall people I fish with, it also shows me that an angled mount makes a lot of sense especially for any power boats where the bow will rise under power. The only other thing I would consider and factor in is the slope of the deck and/or top at rest, vs. at lowest speed plane.

Awesome work.....
I’m planning an 18” dome come spring... last winter I had a couple alum plates welded into the soft top t top at the same
local you show yours..
I’m not sure I’ll be concerned about the beam towards the aft....

Will you use bushings at each bolt to raise the unit?

Great info LS,,, thanks

Hurry Wayne, only 3 months left.... :-)
