"What is the value of the constant C?"
395
It is found on page 137 of Kraus` 1950 edition of "Antennas".

Richard,
You didn't read something correctly.
Reg asked for "C" for a small vertical with uniform current over a
perfect groundplane.
You are off by nearly a factor of 4 times.
For a monopole with uniform current, C=1580
For a monopole with triangular current C= 395
Radiation resistance is four times greater when the antenna has uniform
current.
