- 50MHz J-Pole Antenna
- 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.

- 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.

- Broadband receiving antenna matching
- This article addresses the subject of obtaining the best signal transfer from an antenna to the
typical 50-ohm receiver input over a wide frequency range, with emphasis on medium-wave
(500 – 2000 kHz), encompassing the standard AM broadcast band and the 160-m amateur band.
