I've been looking at making an azimuthal equidistant map. There are several web sites that offer to make one, based on my location, but they all have the same problem. They assume my antenna rotates 360 degrees - so they map the entire world, staarting from my location, and finishing at 20,000km (1/2 earth circumference).
However, my antenna setup only covers 180 degrees. As such, I'm looking for a "half circle" shaped map, that ranges to 40,000 km.
Does such a map exist? Is "azimuthal equidistant" simply the wrong search term, leading me astray?
