Abstract

A long range low frequency antenna having an elongated magnetic core; a coil surrounding the elongated magnetic core; a bobbin; where the elongated magnetic core is introduced in a cavity of the bobbin; and a housing overmolded on the bobbin in a waterproof manner. The antenna also comprises at least one damper located at one extreme of the elongated magnetic core. The at least one damper is made of an elastic and thermally-stable compound having a resin and a first filler including a natural mineral filler. Therefore, 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.
