A 5 band log periodic dipole array - Modified version of the Telerana antenna which was orginially featured in the July 1979 issue of QST. The array is suspended within a framework made of fiberglass poles emanating from a central hub with the ends tied together with light weight rope around the perimeter. 10-15-20-30-40 meter band coverage

Ultimate Portable HF Vertical Antenna - A light and compact antenna that is easy to build, and easy to find parts for. Band coverage is 60 through 10 meters.

KB1SG's Rhombic Pages - Great pages about KB1SG rhombic antennas collected by EI8IC.

ZS6BKW variant of the G5RV - The ZS6BKW variant of the G5RV claims to offer multi-band coverage without the need for a tuner. This article looks at whether or not these claims are valid in a real life installation.

A new method of radio direction finding Priority listing - A method of finding radio sources with antennas based on omni-directionality (the less directional the better coverage). Uses energy levels and some sophisticated math (encompassed in a free software download on the site) to find x,y,z coordinates of the fox relative to the center of your antenna array. Can be overlayed on a GPS map to help you locate in real-time.

France Repeater list - Les relais Francais, map of ham radio repeaters in France

D-Region Absorption Prediction - This map represent the current position of the sun and how a solar flare influence an HF fade. Estimated recovery time is also represented. Includes son java and javascript animations of last two hour conditions

Near-Real-Time F2-Layer Critical Frequency Map - This map can be used to determine the frequencies that will always be returned to the Earth. Transmitted frequencies higher than the indicated contours (which are given in MHz) may penetrate the ionosphere, resulting in lost power to space. The map shows the radio auroral zones as green bands near the northern and southern poles.

IPS - HF Systems MUF maps and prediction charts - These pages provide general propagation advice for HF communicators. Information available includes inferred global propagation conditions, real time HF fadeout coverage charts, regional ionospheric vertical MUF maps and Hourly Area Prediction charts for Astralia and Asia, Europe and North America

APRSa4 - APRS+SA does most of the functions of the original APRS(tm) with a big difference: The maps it uses to plot the locations are Street Atlas 4.0 or 5.0 Maps. This allows great precision in locating objects and stations.
