Beschreibung
Zusammenfassung:	The utility model provides a detection unit and a satellite antenna in-situ detection device, and the detection unit comprises a satellite signal access end, a satellite signal output end, a resistor, an operational amplifier, a first comparator, and a second comparator. The satellite signal access end is connected with one end of the resistor, and the other end of the resistor is connected with the satellite signal output end. The resistor is connected in parallel with the operational amplifier; the output end of the operational amplifier is connected with the first input end of the first comparator; the second input end of the first comparator is connected with a first preset voltage source; the output end of the operational amplifier is connected with the first input end of the second comparator; the second input end of the second comparator is connected with a second preset voltage source. According to the scheme, the satellite signal is accessed based on the satellite signal access end, the voltage diffe
