    Line-of-Sight (LOS) Propagation
    At higher frequencies (VHF/) and above), the Earth's curvature and obstructions block reception unless the transmitting and receiving antennas have mutual visibility. Atmospheric refraction can slightly extend this range, a phenomenon known as tropospheric ducting, which is most prevalent during periods of high solar wind shear [^5].
