Improved telescopic antenna, of the telescopic type formed by a so-called number of tubular fractions of stepped diameters with a diametral strangulation or neck relative to greater diameter than the next characterized because it consists in the lower part or larger diameter of an expander block, with polyethylene preference, of mixed structure and in the same area, externally, of a permanent contact brush even in the oscillations of the integral antenna without machining with independent means of access for its opening and of an insulating and free bushing for the assembly of the bipolar connection cable.
