An experimental eight-shaped loop for HF
The idea behind the double loop is that two properly polarised magnetic fields enhance each other and because the two loops are in parallel

Antenna loop per i 40 metri
Viene descritta una antenna per ricezione in banda 40 metri ed illustrati alcuni problemi relativi all'ascolto su frequenze da 3 a 8 MHz
Antenna boucle magetique
A CV from 5 to 250 pF. A CV starting at 2 pF would be ideal for high frequencies. It is also possible to extend the big loop, but it takes up space
Antenna loop per ricezione onde medie
Migliorare la ricezione in onde medie di un qualsiasi ricevitore casalingo
Antenna magnetic octagonal
A magnetic loop antenna of 4 m octagonal perimeter. The 8 sides are 50 cm, the coupling loop is 30 cm in diameter
Antennas for MSF 60 kHz VLF
Long wires can be used to receive the LF MSF signal but at a wavelength of 5000m its unlikely that any of us will actual use a real long wire

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
