Yagi 4 elements for 27 MHz
Dipolo filare con balun per 27 mHz
dipole centering on channel 20 CB or 27.205 mHz and using a 4 mm copper braid, from the above mentioned formula we get 150 x 0.965 / 27.205 = 5.32 meters
Hentenna freq 27.500
Hentanna is that if it is mounted horizontally, the resulting RF field is vertically polarized and vice versa

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
