- 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.

- J-Pole theory
- The J-Pole antenna is an omnidirectional antenna that can be used for base, mobile and field day stations. It does not need a ground plane, radials or a complicated matching system. The J-Pole can be cheaply, simply and quickly constructed using a variety of techniques, some of which are discussed in this article.
