The WWV antennas are center-fed vertical dipoles.
"The WWV antennas are half-wave vertical antennas that radiate omnidirectional
patterns. There are antennas at the station site for each frequency. Each
antenna is connected to a single transmitter using a rigid coaxial line, and the
site is designed so that no two coaxial lines cross. Each antenna is mounted on
a tower that is approximately one half-wavelength tall. The tallest tower, for
2.5 MHz, is about 60 m tall. The shortest tower, for 20 MHz, is about 7.5 m
tall. The top half of each antenna is a quarter-wavelength radiating element.
The bottom half of each antenna consists of nine quarter-wavelength wires that
connect to the center of the tower and slope downwards to the ground at a 45
degree angle. This sloping skirt functions as the lower half of the radiating
system and also guys the antenna."
