20 meter Vertical with Balun
The balun is rather easy to make you need only a few items. This is a basic balun for a wire antenna, and it worked great for the flagpole

20 Meter Ground Plane Vertical Antenna
It is a multiband vertical antenna composed of several radiating elements of lambda / 4 length supplied by a single coaxial cable

20m vertical antenna
Vertical antennas with a 1/4 or 1/2 wave sizing. Just a happy few build a 5/8 wave vertical antenna. This is remarkable, since the 5/8 has the lowest angle of radiation and has about 1dB more gain compared to 1/4 and 1/2 verticals

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
