A switching voltage generation circuit is provided with a first switch transistor,
a second switch transistor, and a third switch transistor whose base is connected
to the base of the second switch transistor. When a television signal of a UHF
band is to be received, the first switch transistor is turned off, and the second
and third switch transistors are turned on. When a television signal of a high
band of a VHF band is to be received, the first switch transistor is turned on,
and the second and third switch transistors are turned off. When a television signal
of a low band of the VHF band is to be received, the first, second, and third switch
transistors are turned off.
