20 mar 2021 · His plans are easy and you can use the antenna near an AM radio with built in antenna to improve its reception or connect a coupling loop to feed antenna input terminals on radios that can use external antennas.
29 wrz 2021 · Most AM radios (if you purchased one) come with a ferrite rod antenna that’s powerful enough to receive local stations but not powerful enough to give improved reception. So, the external AM loop antenna is a great antenna that would help fix your reception problems and create a discernible signal.
Ferrite rod antenna is a small magnetic loop antenna used in AM broadcast transistor radios for medium & long waveband reception and RFID applications. It is designed with a rod or bar made of ferrites and includes a coil wound around the ferrite rod with the help of a variable tuning capacitor in the radio circuitry.
A common way of improving the reception of weak stations by an AM pocket radio with a relatively small build-in ferrite rod antenna is to place a large tuned loop antenna near it and tune this auxiliary loop antenna to the same reception frequency as the pocket radio.
14 cze 2024 · A ferrite core loop antenna uses a ferrite rod or bar as the core material instead of air. The ferrite core increases the antenna’s inductance and improves its sensitivity and selectivity. Ferrite core loop antennas are more compact than air core antennas and are commonly used in portable AM radios.
24 wrz 2023 · New AM Signal Coupler. Many AM medium wave listeners are looking for solutions to improve the reception performance of their radios. After many attempts, which I don’t want to entertain anyone with, a coupler was created that feeds the external antenna directly into the ferrite antenna.
