A Modified Petlowany Antenna
It is essentially a very short dipole with spiral-wound coils at each end
Antena vertical
Outside of the wave traps there is nothing difficult in the construction of this antenna; the traps are of homemade construction and we will use a simple ingenuity to make them
Vertikal Dipole 10-40m
The modelled inverted-V antenna is full size and will have a higher efficiency than a shortened horizontal dipole. If we consider a full size 1/4 wavelength

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
