Claims

[Scope of utility model registration request]

In a positive tuner in which an antenna loop connected to an input terminal is inductively coupled to a resonant circuit having a resonant line and a variable capacitance diode, and the variable capacitance diode is arranged in a hole formed in a printed circuit board, a second A UHF tuner, characterized in that a hole is formed through which a part of the antenna loop is exposed on the wiring pattern surface side of the printed circuit board.
