ghutch, this drawing is crude, but it does demonstrate the connections related to a 1/4 wave GP (and any other antenna employing a counterpoise).
Braid to radials (or one half a dipole), and center conductor to the vertical.

An earth ground is not a counterpoise. A mast can behave as a counterpoise, but so does the coax when antennas lack sufficient counterpoise. Simply put, the counterpoise is the other half of the antenna.

In the setup you are asking about I see no need to worry with an earth ground. Your mast is enough.
