Corned Fed Delta Loop
The Delta Loop antenna is one of the famous magical antennas, but in reality, the Delta Loop antenna is not as magical as it's reputation. Despite its reputation as a Multi

2 Elements 20m Delta Loop
For this project I started from a Nerio Neri Book antenne.The book describes the building of a HF three bands 10-15-20 aluminium delta loop, but I limited the design to 20m band only
2 element 40 mt parasitic switchable array
He used 3/8 electrical wavelength feedlines to each element. He would transmit with a single sloper the other ones acted as reflectors. Why? Because the 3/8 wavelength feedline going to the other slopers

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
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
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening facto
