1. A long range low frequency antenna, comprising:
an elongated magnetic core;
a coil surrounding the elongated magnetic core;
a bobbin;
the elongated magnetic core introduced in a cavity of the bobbin;
a housing overmolded on the bobbin in a waterproof manner;
at least one damper located at one extreme of the elongated magnetic core, the at least one damper made of an elastic and thermally-stable compound comprising a resin and a first filler including a natural mineral filler, whereby longitudinal dilatations, shrinkage, mechanical shocks, and vibrations of the elongated magnetic core are absorbed by the at least one damper, avoiding an impact over an inductance variation of the coil.
