    • An antenna that comprises a rod, a movable coil, and a holding section which holds the movable coil in a manner that allows the movable coil to slide in and out of the holding section. When the movable coil is drawn into the holding section, the holding section tunes to a particular desired frequencies in the upper portion of the VHF band and the UHF band; for example, 144 MHz and 430 MHz. When the movable coil is out of the holding section, the holding section, the rod, and the portion of the movable coil outside the holding section form antenna element of a center-loading type that tunes to frequencies in the HF band and the lower portion of the VHF band; for example, frequencies in the range of 3MHz to 50MHz. The tuning frequency is varied by sliding the position of the coil.
