WebWe've been using high-frequency (HF) communications for many years. Throughout the 1950's and 1960's HF sky-wave systems were was the backbone of our long-distance communication. The advent of communications satellites in the late 1960's and early 1970's brought a change of philosophy about long-distance communications. Websky wave: [noun] a radio wave that is propagated by means of the ionosphere.
WebSky wave can be separated from ground wave for frequencies above 100 KHz. Logically, the ground wave has a larger transmission loss. Absorption in daytime. Applications : Long-rangenavigation and marine communication, radio beacons. MF Medium Frequency: Sky wave separates from ground wave. Ground wave gives usable signal strength up to 2
