Default broadband 3G radar

I have bought a Simrad 3G radar and am trying to figure the best height to mount it on the mast. According to the 3G/4G manual it is best to mount it so that you get a clear view from the radar beam at a 25 degree angle down. Less acceptable is an angle from the radar of 12.5 degree according to the pictures. So to me the specs should be a vertical beam width of 50 degrees not the 25 degree that is listed?
For the Simrad 2K radar the specs say it is a vertical beam width of 30 degrees and their pictures show that the radar should have a clear view of 15 degrees.
If this is correct it appears that the broadband has almost twice as much vertical beam width. Does this seem right?
Last point, if this is true then I would guess that broadband radar would be less susceptible to heeling affecting the quality of the radar signal? If so I would be more likely to go to a fix mount vice self leveling.....

thanks for any input,

Richard
