A 5 element beam for 10 meter band - Here is a very simple 5 element covering the entire 10 meter band (28.000-29.700) with a swr of less than 1.4 at the band edges

The All Copper X-Beam for 17 Meters - WA2UGT X-beam antenna for 17 meters band

The 2-Element-HB9CV-Beam  ^updated - The HB9CV-Beam is a 2-Element-Yagi with two driven elements and was introduced by Rudolf Baumgartner, HB9CV in the 1950ies. The Beam is a coax-feeded version of the ZL-Special Construction by DK7ZB for 2m, 6m and 10m

6 meter HexBeam antenna - SP3FHI hexbeam antenna built with bamboo sticks

W4TI - Installing the Hexbeam - HX-B5i five band HexBeam installation by w4ti

Hex-Beam Video - A rotating HexBeam antenna video from F5NZY in Paris France

G3TXQ Broadband Hexagonal Beam - MW0JZE Manufacturer of the G3TXQ Broadband Hexagonal Beam - HexBeam Antennas

OptiBeam - optimum short-wave antennas, developed by hams for hams

PA2P Map WW-locator - Google Maps utility map by PA2P, with WW-locator and lat/lon. A Google Maps mash-up, also using the code of F6FVY, but with extra options.

Amateur Radio Map of Italy - Map of italy with amateur radio prefixes and grid squares

LU Argentina prefix map - LU Argentina Country CALL division Antarctic and South Atlantic prefixes and sufixes

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.

NEC4WIN - NEC4WIN is a 32 bits commercial antenna simulation software based on MININEC3 developed by the Naval Ocean Systems Center in the 70s and 80s. It runs under Windows and can be used to simulate, analyze and optimize wire antennas, beams, verticals, etc. NEC4WIN has limitations. They are the same as Mininec3 on which the engine is based.

WorkedGrids - Ham Log Mapping software freeware for Windows, displays a map showing the amateur radio grid squares contacted and logged in using a third-party logging program by: Bertrand Zauhar, VE2ZAZ

Pizza - This program allows both great-circle (polar) and rectangular projections of the world. The great-circle map is centered on any specified latitude and longitude (the "home" location). The rectangular projection is shown with the home longitude in the middle of the screen.
