Vehicle rod aerial for several separate frequency ranges - comprises 400 mm rod with coiled lambda-4 conductors for lower frequency range with common foot point

The length (l1) of the aerial component (1) corresponds to one quarter of the average operating wavelength lambda1 for the radio receiver as lower and lowermost frequency range. A section (2) from a footprint (A) to a further point (B) has a specific length (l2) acts as radiator for an upper frequency with an average operating wavelength lambda2, e.g. for the mobile radio in the range 450 to 465 MHz. A parallel oscillating circuit (3) acts as stop circuit for the upper frequency range. A provision for this is an additional aerial conductor (4) which is insulator against the first such conductor (1), and is capacitively or galvanically coupled with the parallel oscillating circuit (3) at a specific point (C). Through the influence of the additional aerial conductor (4) a low-ohmic real impedance appertains for the upper frequency range at the specific point (C). ADVANTAGE - Good power values in all ranges.
