J-Pole Antennas for 2 Meters  ^pop - This paper describes two types of 2 meter J-Pole antennas, one made of copper pipe and a roll-up J-pole made of TV twin lead. The figures give the details of the dimensions, components and construction.

Compact Restricted Space 40 Meter Wire Antenna - An inexpensive easy to construct compact 40 meter wire antenna that will fit in a 20 feet by 20 feet space

A Feasible Full Sized 40 Meter Beam - This project started as a result of renewed interest in 40 meters coupled with the desire for an antenna system that would be more effective than the simple dipole.

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.

J-Pole theory  ^pop - 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.

A Small Wire Loop Antennas for 160 meters  ^pop - Low noise, receive only coax loop antennas for 160 - 10 meters HF bands

MOXON Antenna Project - The MOXON antenna can provide radio amateurs with an excellent antenna system that is easy to homebrew and usually does not require any adjustment if made according to the dimensions specified by its designer. A typical MOXON rectangle can be built in a few hours, using X type of spreaders arrangement as discussed on this web site.
