The Crossed Field Antenna (CFA) is one of the applications of Correction of Maxwell's Equations which was used over 150 years ago which was proved these days that the Magnetic Field Source is only the Displacement Current not the Conduction Current . These Corrections was made by an Egyptian Doctor Engineer Fathi Kabbary , who reached the New Correct Theory which shows that the height and efficiency of the antenna doesn't depend on the wavelength

The website offers a comprehensive guide on high-frequency (HF) skywave propagation for amateur radio operators. It explains HF radio propagation fundamentals, including electromagnetic wave properties, HF bands, and propagation modes like skywave, ground wave, and line-of-sight. The site focuses on the ionosphere's critical role, influenced by solar activity, in refracting HF waves for long-distance communication. Real-time monitoring tools such as DX clusters, beacons, and digital modes like FT8 assist users in tracking band activity and propagation conditions globally. Forecasting methods are detailed, highlighting scientific insights into solar-terrestrial interactions and ionospheric variability. The guide also covers advanced topics like NVIS and gray line propagation, ionosonde data, and propagation prediction models, making it a valuable resource for ham radio enthusiasts aiming to optimize communications
