What is HFTA

HFTA stands for High-Frequency Terrain Assessment. Some documentation refers to it as High-Frequency Terrain Analysis.

HFTA is a software tool that generates the vertical radiation pattern of horizontally polarized antennas taking into account the profile of the surrounding terrain. The irregularity of local terrain has a profound effect on vertical radiation patterns. Note that HFTA does not compute radiation patterns for vertically polarized antenna radiation.
