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.

AMRAD Active LF Antenna - The AMRAD Active LF Antenna. You can tune into LF activity with this easy-tobuild and erect active antenna. As a bonus, you get MF and HF coverage, too—not to mention world-class performance

Inexpensive GPS mobile Antenna - An inexpensive external GPS antenna, for 1.5 GHz band for GPS receiver, If you operate APRS or just need an external antenna for your GPS receiver, here’s one that is easy to build yet offers surprisingly good performance in a compact size. Best of all, it uses commonly available components and materials.

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.
