6:1 Voltage Balun
Requiring a balun to feed a balanced antenna from an un-balanced load with a impedance step up from 50ohms to 300ohms, a 1:6
9:1 transformer
A balanced antenna from an un-balanced load with a impedance step up from 50ohms to 300ohms, a 1:6 Voltage balun design using two L15 ferrite toroid cores was selected
A 9:1 Balun For Your End Fed Antenna
unun transformer unbalanced to unbalanced. The raw End-Fed antenna will go through impedance swings as high as 5K Ohms,or more, at even multiples of its 1/4 wavelength design frequency

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
