Building a 4 Element Cubical Quad
Recommend building a 4 element quad. Four elements gives the highest gain to size ratio of any type of beam in existence
The HB9CV 11 meter
The HB9CV antenna is smaler than a 3el. conventional Yagi but you get the same gain and caracteristics
Skypper 3 element for 11m
3 elements wire Yagi for 11 meter we call it the Skypper due to the manufacturer Alex 1SD019
Antenna Bazzoka for 27.500 MHz
The dipole antennas built with coaxial cables with short-circuited ends are also called bazooka

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
