I use the “wire” antenna port for temporary setups with the supplied wire antenna.
At home I use the “F” connector to feed my outdoor antenna using RG-58 coax.
I don’t use the “wire” antenna port with my outdoor antenna as the auto-tuner is designed to work into a high impedance which the wire antenna provided would have. The auto-tuner usually can’t find an adequate “tune” when connected to the lower impedance outdoor antenna.
I suppose if a “wire” antenna of the proper length was used, it would present an impedance high enough for the auto-tuner to work with. A wire somewhere between 3/8 to 1/2 wavelength would probably work. Of course at these frequencies that gets to be a fairly long antenna.
