1984 3607 aft cabin. I purchased the vessel with an open array radar mounted on a platform between the top of the windshield and below the splash screen of the flybridge. Although there is cabling, there was no display unit when I purchased the vessel.
Im now considering adding a functioning radar. So Im debating on where to mount the open array/dome
The boat has a nice radar arch installed that would put the array/dome well above my head on the upper helm and would seem to be the best/most likely installation location.
However, I spend a good portion of my time travelling the Erie Canal that has some low bridges. The arch itself puts my bridge draft at 15 ft. Adding in a radar array on top of the arch could potentially restrict my travel (no the arch cannot be lowered as it is a structural component of the aft deck hard top)
As I said, the previous installation of radar has the array mounted on the a platform forward of the upper helm between the windshields and the flybridge.
I have done a bit of research of the potential harm to persons if the active array were left in that location. It appears that I would not be harming people by doing so.
I also realize that installing a new array in that forward position would create a significant "blind spot" of approx 180 degrees from port and starboard to aft - essentially, I would be blind to what is behind me.

So, I wanted to query this forum. What are your thoughts?
Does anyone have any documented reliable sources of information that stipulate harm to humans?
What are your thought on losing 180 degrees of visibility to your stern?
