The Blosenbergturm is a self-radiating tower insulated against ground, i.e. the entire tower structure is used as an antenna. With a total height of it is currently the sixth tallest structure in Switzerland. It has a cabin at a height of , containing a coil for feeding the pinnacle, which is insulated against the rest of the tower, separately with high frequency power. Originally the tower was used as a dipole antenna, fed from the cabin.
