Thanks, guys.
Denny - Thank you for the solid data. I was planning on paying a friend's electronics guy to install everything because I'm afraid of messing up my new top. The install guy thinks I'm going to need a radar dome mount... without seeing the boat first. I'm puzzled by this.

I told him that the fabricator, who made the top, said that the 1 degree angle down in the top should be enough and that the radar does not need a mount. Frankly, I think the electronics guy simply wants to sell me a mount.

I'm not gonna lie. I do like the finished look that the mount gives the radar dome. But I question its "necessity."
