In a seven-year project to adopt a technology used on Navy ships, NIST has installed new antennas encased in fiberglass rather than traditional steel supports, to resist corrosion from the salty ocean air. ... NIST staff believe the project is the first demonstration of high-powered, high-frequency fiberglass antennas on land.Have any of you heard any changes in WWVH service? I continue to get decent WWVH reception here during the day on 10 mhz and 15 mhz. I'll have to try for 2.5 mhz and 5 mhz at night.
