The Newmar Ground Plate is cast of porous bronze
material which, when immersed in water magnifies the contact area
with the water many times beyond by its outer dimensions. Water
penetrates through the plate, creating a ground that is superior to
a simple metal plate of the same size. This provides low impedance
ground which is necessary for the proper operation of many types of
electronics. The shoe/plate is installed on the outside of the
hull, below the waterline. The aerodynamic shape minimizes
drag.
