Dear Stefan, LF Group,


Hmm, maybe someone from the UK can explain the difference between aerial and antenna? Is there a difference?

Antenna = general term for a device that converts an electrical signal into an electromagnetic wave, or vice-versa.

Aerial = structure of wires (or perhaps other pieces of metal) suspended above the ground, forming an antenna.

So for LF, antennas are nearly always aerials. But many types of antenna are not aerials, e.g. microstrip patches, horns, dielectric rods, etc., etc... But often the two words are used interchangeably.

Cheers, Jim Moritz
