Radar newbie here and I am going to install a Garmin 24 dome on top of a pilot house roof. Unfortunately, it will have to go directly behind the spot light in the pic. The spot light is exactly 10" high. The radar will be mounted on a 6" tower with a 4 degree down angle. The dome itself is just shy of 10" so the mount as a whole will be 16" tall. Will the spot light forever be an "image" on the screen? The mount I want only comes in 6" or 12". Do you think 12" would look awkward being so tall? I don't know if the company will custom make a 10" version as they are closed until 2/14.
