The video shows the inside of the box which, as you’d expect, is a toroid with a few turns of wire. The proposed antenna is an end-fed dipole fed with the unun. These are somewhat controversial ...

A so-called random wire antenna is an end fed antenna. One end goes straight into the rig, often with no feedline, and the other end in the air attached to something as high as you can find, as ...
