It is not always convenient to operate an FM receiver, whose antenna is a meter long piece of wire, and in some cases it is sometimes impossible. To add comfort while listening to the radio, the author of the channel “Valery Samodelkin” shows how to build a miniature, helical FM antenna that has high sensitivity, looks stylish and does not cause any hassle in its placement.

  • Insulated wire 77 cm long (distance 1/4 FM wavelength).
  • Protective cap from the lamp base (they are thrown away when buying).
