Hello,
It can or cannot. It depends on your required coverage area, soil
characteristics and ground network. Assuming local coverage, it will
definitely work less then a vertical quarter or half wave fed over a
very good ground network.
When you have a relative bad ground circuit, you may only need a
capacitor in series with the antenna wire to do the matching. When you
have a good ground, you need an additional inductor.
When you provide some more info, you might get better feedback.
