WWV National Institute of Standards and Technology (NIST) UTC time, broadcasting on 5.000 MHz. WWV is located in Fort Collins, Colorado, about 100 kilometers north of Denver.

The station radiates 10,000 W on 5, 10, and 15 MHz; and 2500 W on 2.5 and 20 MHz.

Antennas are half-wave vertical antennas that radiate omnidirectional patterns. There are actually 5 antennas at the station site, one 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 9 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.

I believe this is the French coastguard, either Corsen or La Garde, Mediterranean Coast. I can only assume she’s giving out a weather report as i dont speak a word of French!
