9 element yagi for 2 meters band  ^{updated  pop} - A simple design of a 9 elem. yagi antenna for 2 meters band

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.

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.

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.

Super J-Pole plans - The super J-pole is a regular J-pole antenna with a 1/2 wave element mounted above with a 1/2 wave phasing harness connecting the element to the bottom part of the J-pole. The antenna can be built for any band, but I built mine for 2 meters

J Pole antennas variations on a theme - Twin lead jpole, ladder line jpole, copper cactus j pole, material list to build your own jpole antenna and a brief history of Jpole antennas.

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.

Easy J-pole antenna  ^pop - Everybody says keep one in your bag, nobody seems to make one work right. Here's the straight scoop on why the J-pole is not an easy antenna to duplicate!

Building the J-Pole Antenna - They're tricky, but they're worth it! By KA1FSB

HF J-Pole antenna - A Simple Nondirectional Antenna for Ten Meters QST February 1950, Easy to build J-Pole antenna for restricted space.

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.
