πŸ“» Fun Fact & Pro Tip

Fun Fact: NVIS antennas are commonly used by military and emergency services because they allow reliable regional communication without relying on repeaters or infrastructure.

Pro Tip: When setting up an NVIS antenna, height matters β€” typically 0.1–0.25 wavelength above ground gives the best high-angle radiation for local coverage.
