Small knife or medium grit sandpaper. 2. Make an antenna. The antenna is one of the simplest parts of a homemade radio: all you need is a long piece of wire. Ideally, the wire should be 50 feet (15.2 m) long, but if you don’t have that much, you can use as little as 15 or 20 feet (4.6 or 6.1 m).

Any antenna that is less than 1/2 wavelength long and less than 1/2 wavelength high will start to loose efficiency when shortened or lowered. (1/4 wave verticals must also be at least 1/4 wavelength long and have an almost perfect ground plane). So for HF frequencies if you want to go a similar route you should look into magnetic loop antennas.Apr 11, 2019 ...
