the two wires coming out of that box form a loop. You can stick ... alligator clips, or a ferrite bar that can couple to a radio’s internal antenna. You probably need SMA for a modern radio ...

The built-in antenna in most receivers – a coil and a ferrite rod – is not sufficient for clear reception. An external antenna can usually greatly improve reception. The loop antenna is a proven ...

However, a whip antenna is much less convenient for the user of the receiver, and the obvious question is whether a ferrite rod could be used instead at HF. Yet another possibility is the loop or ...

Used on a coaxial cable going out to the antenna system ... If you have a ground loop, such that not all of your return current is through the coax shield, the ferrite will saturate — and quickly ...
