Radio station WWVH in Hawaii, operated since 1948 by the National Institute of Standards and Technology (NIST) to broadcast time, frequency and other announcements, recently powered up innovative replacement antennas. NIST has installed new antennas encased in fiberglass instead of traditional steel supports to resist corrosion from the salty ocean air. The fiberglass design will reduce maintenance and repair costs as well as climbing hazards to staff. Users of the radio broadcast service may notice reduced signal down-time.
NIST time and frequency experts believe the project is the first demonstration of high-powered, high-frequency fiberglass antennas on land. For more information, go to [link removed].
