The invention is directed to an antenna particularly suited for use on a motor vehicle.
Antennas for motor vehicles generally include a base secured to the body of the car and a rod that comprises the active element of the antenna.
In known applications, the rod of the antenna can be fixed or oriented with respect to the base and it may be connected to the base itself by a removable connection, for example, screws, pins and the like.
One of the drawbacks of known antennas is that unauthorized persons can readily remove the antenna from the support with appropriate tools which are easily acquired.
The present invention seeks to eliminate or deter this disadvantage. In particular, one aim of the invention is to provide an antenna suitable for installation on a motor vehicle that would have anti-theft features, and particulary features for preventing the removal of the rod from the support base.
Another aim of the invention is to provide an antenna with such anti-theft features, both on an arrangement having a fixed rod or an adjustable rod.
