Multiband delta loop by DL2HCB  ^pop - A 10-20 meters coverage delta loop antenna by DL2HCB

17 Meter Coaxial Moxon Antenna - 17 m reduced size coaxial moxon rectangle, an exercise with an MFJ 259B plans by N0KHQ

20m delta loop  ^pop - This antenna is fed for vertical polarisation, to give a low angle of radiation for DX and also a nearly omni-directional radiation pattern

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.

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.

Moxon rectangles for 6 Meters - Moxon antenna for 50 mhz, The Moxon rectangle is a quite broad-band antenna, but it is not quite broad enough to cover the entire band.

H5ANX Mk4 Delta Loop Design - Delta loop antennas design by Sajid Rahim

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.
