WebA good way to locate radio-frequency interference (RFI) in the HF bands is with a small direction finding antenna and a portable radio. Here is a simple antenna design that is effective from 3 to 22 MHz. Based on a resonant magnetic loop, it has high transducer gain (high sensitivity), and also very good directionality. You can build it cheaply ... WebThe gain and input impedance of the antenna is dependent on the length of the whip element, compared to a wavelength, but also on the size and shape of the ground plane used (if any).
