PURPOSE:To receive a high band of VHF and UHF with a high gain by using the whole element of the television antenna which is used to receive the low band and high band of VHF and all of UHF. CONSTITUTION:A 1st element 91 has 7/8 wavelength of UHF and operates as an antenna for UHF on the whole. Further, this element has 1/4 wavelength of the low band of VHF through an extension coil 83 interposed halfway and operates as an antenna for the low band of VHF. The length of a 2nd element 92 plus the part from the intermediate point to the tip of the 1st element 91 to which the element is connected corresponds to 7/8 wavelength of UHF and the entirety operates as an antenna for UHF. Further, the entirety has 1/4 wavelength of the high band of VHF through a shortened capacitor 86 interposed halfway and operates as an antenna for the high band of VHF on the whole. |
