The WonderBar Mark III 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.
