WebJun 7, 2024 · Since any electromagnetic radiation consists of both a time-varying electric and magnetic field, any loop of wire can theoretically be used as an antenna. The … WebSmall receiving antennas, such as the ferrite loopstick antennas used in AM radios, also have low radiation resistance, and thus produce very low output. However at frequencies below about 20 MHz this is not such a problem, since a weak signal from the antenna can simply be amplified in the receiver.
WebAug 25, 2024 · 3. There is an article on wikipedia about loop antennas. It shows like an AM radio's antenna with the ferrite rod and says this: This greater conductance channels thousands of times more magnetic power through the rod, and hence through the loop, allowing the physically small antenna to have a larger effective area. WebFeb 19, 2024 · The Beverage antenna or "wave antenna" is a very long wire receiving antenna mainly used in the low frequency and medium frequency radio bands, invented by Harold H. Beverage in 1921. ... Then couple the ferrite bar/rod to your radio's ferrite antenna. You can even run it through a length of coaxial cable, though better results will …
WebSep 11, 2024 · I doubt that the small ferrite core really behaves well between the stated frequency range 10kHz to 30 MHz. So far I did not find anyone who uses compared of performance of Möbius based receive loop antennas, with the round long Ferrite rods from stand alone AM radios or the the smaller flat Ferrite Rods in portable AM radios.
