Ionospheric bounce

Web30 jul. 2002 · Radio signals from 1-50 MHz often bounce from earth to ionosphere and back, and often several times to get to your radio. That signal may be not propagating well via ground-wave to your current location, and the skywaves are effectively bouncing right over your head. Here are a few links to get you started: http://solar-center.stanford.edu/SID/activities/ionosphere.html

WebRadio waves transmitted by antennas in certain directions are bent or even reflected back to Earth by the ionosphere, as illustrated in Figure 5. They may bounce off Earth and be reflected by the ionosphere repeatedly, making radio transmission around the globe possible. Long-distance communication is further facilitated by the so-called ground ... Webionospheric-bounce communication, and try VHF or UHF radio signaling, instead. But, since signals at these frequencies would not propagate very far on a spherical earth (simply line-of-sight) one might use the moon as a reflector in the sky, much as successful shortwave communicators use the ionosphere as a "reflector."

WebThe skywave can bounce once, or many times, between the ionosphere and the Earth, before reception by a radio receiver. We experience skywave reception with long-distance AM radio reception, as well as for shortwave radio and many of the radio bands used by amateur radio “hams.” WebA discone will give you more like a 10 to 1 bandwidth, but the reason that you don't see them much at hf is down to the size and mechanical complexity, and the fact that you don't need continuous coverage, so it
