The A-Z-G terminals are used this way with a single wire antenna:
Connect A to the single wire antenna, connect Z to G and connect G to ground (Earth).
With a doublet antenna transmission line using two twisted wires, connect one wire to A and the other wire to Z, do not connect Z to G. Keep the G connected to earth ground.
The doublet antenna commonly uses a twisted pair of wires and is used as a transmission line to the antenna. The type of connection at the antenna will vary as the transmission line has a characteristic impedance, the antenna connection must match that, yet be broadband for all the shortwave frequencies. The twisted pair transmission line cancels out most noises from inside the home, a good choice if the radio is located well inside the home.
