If the frequency is 3.7 megahertz, the antenna length is 38.554 meters, and the dipole leg length is 19.277 meters.
The formulae to calculate the dipole antenna and leg length are:
L = 468 / f
l = L /2
where:
L - Length of the dipole antenna;
l - Length of each arm of the dipole; and
f - Frequency.
