4 meter delta loop
The Delta loop has an impedance of about 100 ohms and to match it we use a quarter wave of 75 ohm coax in series to with the 50 ohm feeder

AM loop antennas
I used 24 gauge wire and had to wrap 18 turns to get an inductance of about 250 uH. With a 365 pF Variable air capacitor
Calcolo Loop Magnetica
Non usare il tubo del loop, con un diametro troppo piccolo perche va a discapito dell'efficienza
Magnetic loop antenna
The story started with having a remaining coaxial cable 6 meters 7/8 beschikbaar, which is used in the Amsterdam metro tunnel for the construction of a new communication system in which I was involved on a project basis
Rockloop Antenna
Years ago I started experimenting on magnetic loops & Co; I like the idea of narrow resonant aerials

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
