20 Meter Vertical Antennas: Designs and Projects
Find schematics and construction guides for 20 meter vertical antennas, including single-band and multi-band options.
Vertical antennas for the 20-meter band are popular with hams for their low-angle radiation, which is excellent for working DX. Many operators choose verticals for their relatively small footprint, making them suitable for smaller lots or portable operations. These antennas can be simple quarter-wave designs or more complex arrays, often requiring a good radial system for optimal performance on the 14 MHz band.
This category features numerous antenna projects, from simple wire J-poles for 20 meters to more elaborate designs like the T-Monopole by AA5TB or the vertical Moxon. Hams can find detailed guides for building portable multi-band verticals, such as those suitable for Field Day operations, or specialized designs like the Vertical Buddi Beam. Many projects include construction details, performance insights, and even modeling data using tools like 4Nec2 to help operators build effective antennas for their stations.
