K2YWE's Compact 160m Lazy-U Antenna
- This compact 160m antenna is a half-wave dipole with a vertical section. It requires no radials and has worked well for me.
20m delta loop
pop
- This antenna is fed for vertical polarisation, to give a low angle of radiation for DX and also a nearly omni-directional radiation pattern

50MHz J-Pole Antenna
pop
- Need a general purpose antenna on the magic band? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub.

EH antennas and CFA antenna
- Many antennas function because of common mode currents, rather than working in spite of them. Two popular examples are CFA and EH antennas. Another recent example, appearing in Antennex's compact antenna articles, is a thick stub "vertical" with no counterpoise.
End-fed vertical j-pole and horizontal zepp vertical
- There are many incorrect ideas and claims surrounding end-fed vertical antennas (like the I-Max 2000), end fed horizontal antennas, Zepp, and J-pole antennas. This article describes it.
