Excellent technical reference article by Steve G3TXQ:
1. Arrival angles
In “Hexbeam Height (Part 1)” we looked at how a Hexbeam’s height above ground affected its directivity and its tuning. We came to the conclusion that “higher is better” when the objective is to maximise the antenna’s performance at very low take-off angles. However, depending on our operating interests this may not be an appropriate criteria; so in this section we will look in more detail at signal arrival-angles for different HF bands and paths, and how they play against the Hexbeam’s height.
