Match for Yagis
It is a well known phenomenon, that the radiators resistance in a Yagi-structure drops down by adding parasitic elements to a dipole as a radiating element

Maria Maluca Antenna 20 - 6m
Now it should be a directional antenna for shortwave. For the time being for portable activities, possibly later stationary. After a lot of research, I have shortened directional antennas
