Given 1 volt per m as the field strength, and a 1-m antenna parallel to
the electric vector of the wave, the open-circuit voltage at the end of
the wire is 1 volt.

Relative to what? The other terminal has to be extremely close to the
end of the wire in order for the voltage to be single valued.

The best you can get across the receiver input is
0.5 volt when there is a conjugate match between the receiver and the
antennna.

Sorry, that's not just a little wrong, it's wrong by orders of
magnitude. For example, a 1 meter long 10 mm diameter dipole, terminated
in the complex conjugate of its self impedance (load Z = 0.8855 + j6030
ohms), in a 1 V/m field, has about 1667 volts across the load. Hardly a
half volt!
