A lossless quarter-wave monopole has an radiation resistance of 35 ohms.
To that all losses will be added and the result is the feed point impedance.
That will never have an impedance of 12 ohms but 40-50 ohms or more.

A resonant quarter-wave monopole over a decent ground might have an
impedance of about 12 ohms.
