The 40m 4-square on a 4-channel Oscilloscope
the verticals for the 40m 4-square
Three-Phase
Three halfwave verticals phased with homebrew ladder line
Two element phased vertica system for 40 meter
The Two Verticals are spaced 32 feet apart
VDA Vertical Dipole Array
The VDA is It consists of 2 elements, the driven element and a parasitic one, the reflector

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
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
