All the components required in a radio receiving system have to be optimized to produce the best possible design. And a very important part of this process is selection of the right antenna. In the HF range in particular, a lot of importance attaches to matching the antenna – especially its vertical radiation patterns – to the reception task. Signals with high-angle radiation as well as those with a low angle of incidence need to be received, and both short and global distances have to be covered without a gap.
