Dipole 14-50 Mhz
The dipoles are not in contact, are tightly coupled and spaced approximately 7cm apart. This technique is quite applicable for a larger number of dipoles

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 aerial
About ten feet of 22mm copper pipe and about eight feet of 15mm copper pipe
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
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
