- 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.

- Double Half-Delta Loop RX Antenna
- This wire antenna was developed to offer for a small, low-band, ground independent directional receiving antenna, it requires only two support poles. It is basically composed by two interconnected half delta loops and is better than a single flag or EWE, and almost as good as two phased EWE in the same space.
