I think you will find that a fixed mount will heel the same number of
degrees whether mounted high or low. In other words, the base of your mast
is at the same angle to the horizon as the top. The difference to a radar
would seem to be simply the height. Higher sees further, but I suppose could
overlook very close objects.

Best Regards,

I'm no expert on radar; but, I understand that for a fixed-mount radar lower
is better than higher as the resolution of the signal depends on being level
or close to level with the horizon.  I can't tell you the effect of a stern
mount vs. a mast mount.  There is a gimbled mount for marine radars that is
designed to keep your dome level at any degree of heel.  I don't know how a
given sea state may affect the resolution; but, seems it must to some
degree.  Sorry, I can't remember where I got this information.
