Vertical half-wave aerials for 4m
For vertical use, it is much more mechanically convenient to end-feed an antenna: this will allow it to be mounted higher, and avoids distortion of its omnidirectional polar
Vertical Pancake Dipole 10-20 Meters
The antenna easily loaded 10-20 meters in the vertical configuration but it didnt do well for me on 10 and 17 meters as a horizontal dipole

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
