Wire antennas for the low bands
I have experimented with a variety of wire antennas. Any configurations have to fit in my 100ft long by 40ft wide garden

L'antenna Windom
Windom did some experiments and found that if the dipole feeding point was moved, the amplitude of the currents for the different bands was such as to have the possibility of resonance on the even harmonics
L'antenne G5RV
The G5RV antenna is named after the call sign of its creator, a radio amateur from England
Antenna Bobtail 3el. per i 40m
Half square o bobtail curtain, con un basso angolo di radiazione
Le dipole symetrise par gamma-match
To avoid corrosion phenomena at the connections it is recommended to use the same metal to make the radiating strand

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
