That sounds about right. As you put a good ground system under it, that value
will come down, and the efficiency will come up.
Many add extra antenna wire that pushes the current up the wire, this also
raises the impedance, hopefully to near 50 ohms with the right length.
A capacitor (variable, then fixed) in series at the feed point can cancel the
added inductance.

What should the Z be for a 1/4 wave inv l, with the radials attached to a
radial plate? Mine seems to be 60 ohms or so....
