Build for 14 MHz magnetic loop antenna
20 Meter Loop Antenna–it’s such a simple project and requires no special order components. In fact, all of the components save, perhaps, the antenna connector can be purchased at a DIY store

1.8 a 21 mhz Magnetic loop
For 80 160 connect capacitors accros a & b, use about 390pf
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
2m loop full wave antenna
Le caratteristiche piu' interessanti di questa antenna sono, alimentazione diretta in cavo coassiale senza adattatori
14-30 MHz Magnetic Loop Antenna
A high voltage shunt capacitor made from 154 cm 60.5 inches of RG-58/U coaxial cable approximately 150 pF
Two-monoband-magnetic-loop-antennas
The loop for the 21-28 Mhz bands is soldered the ends of the heliax to the butterfly capacitor and to a piece of RG-58 coax

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
