Balcony antenna extension
I used to use an old CB 27 MHz half-wave antenna which had a broken matching coil. this I used as a 1/4 - wave antenna for 14 MHz, after removing the matching coil

Dipole vertical demi-onde
At a height of lambda / 4 from the ground, the radiation pattern is close to that of a vertical quarter wave on a ground plane, with a starting angle of about 15 degrees on the horizon, favorable to the DX
Half-wave vertical dipole 14 MHz
building a half wave antenna for 20m radiator I took 10 meter wire, 2.5 mm thick
Effective HF Mobile Antennas
One of the problems with HF mobile operation, especially on 160, 80 or 40 Meters is antenna efficiency. The problem has been addressed in numerous publications for years
Groundplane antenna
This is the antenna I have found to be the most effective limited space radiator that I have ever used

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
