- Crossed Field Antenna
- The Crossed Field Antenna (CFA) is one of the applications of Correction of Maxwell's Equations which was used over 150 years ago which was proved these days that the Magnetic Field Source is only the Displacement Current not the Conduction Current .
These Corrections was made by an Egyptian Doctor Engineer Fathi Kabbary , who reached the New Correct Theory which shows that the height and efficiency of the antenna doesn't depend on the wavelength

- VK2ABQ Wire Beams
- The VK2ABQ wire beam is described in Les Moxon's HF Antennas for all Locations which also contains the original references, but they are rather difficult to find. The VK2ABQ antenna is a planar wire beam that can be constructed from a single hub and four spreaders.

- Portable Loop Antenna
- This loop it is small and light enough to carry while operating, it disassembles into small but rugged pieces that fit easily in a backpack or gym bag, and it can be tuned from 14 MHz to 30 MHz.
This tunable magnetic loop antenna is my contribution to the well established art of amateur loop making. Can be tuned from 14 MHz to 30 MHz.
