 The longest terrestrial contact ever reported on 2 meters (146 MHz) was between a station in Italy and a station in South Africa, a distance of 7784 km, using anomalous enhancement (TE) of the ionosphere over the geomagnetic equator.This enhancement is known as TE, or trans-equatorial propagation and (usually) occurs at latitudes 2500–3000 km within either side of the equator.Aurora
