Abstract: PROBLEM TO BE SOLVED: To provide a receiving unit for a terrestrial digital broadcasting retransmission apparatus which can surely detect a radio wave wraparound from a transmitting antenna to its own receiving antenna. SOLUTION: When an MPU (micro-processing unit) 43 detects a wraparound, it makes an output amplifier of the receiving unit into the off state, changes sequentially the oscillation frequency of a local oscillator 54 with an interval of 100 kHz, takes in an IF signal inputted from an input terminal 51 via a mixer 53 and a filter 55, and stores the level of the signal into a memory via an amplifier 56, a detector 57, and a DC amplifier 58. Subsequently, the MPU 43 makes the output amplifier of the receiving unit to be in the on-state, changes again sequentially the oscillation frequency of the local oscillator 54 with an interval of 100 kHz from the initial state, and compares the output signal level of the DC amplifier 58 from this operation with the stored value in the memory.  It is determined that a radio wave wraparound occur if this comparison value is above a setting value, and an abnormality indicator is lit on.
