Ferrite receiving antennas
Did you know?
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. WebMar 26, 2024 · My eventual goal is to use this antenna in a DIY MW/LW receiver project, with the TA 7642 AM radio IC. This is my first DIY antenna, 120 turns of 28 AWG …
