The utility model provides a UHF band data acquisition platform which comprises a Yagi directional antenna which receives the signal in a UHF band, a first radio frequency distributer which is connected with the Yagi directional antenna and divides the signal in the UHF band into two paths which are a first path of signal and a second path of signal, a spectrum analyzer which is connected with the first radio frequency distributer and receives the first path of signal, and a PC machine which is connected with the spectrum analyzer through a serial data line and controls the spectrum analyzer to measure and collect first path of signal to obtain collection data. According to the UHF band data acquisition platform, the 24-hour uninterrupted signal measurement can be realized, passband power and measurement time are recorded, turning can be carried out rapidly, the time of scanning UHF television broadcast bands (DS13-DS48) for one time is about 120 seconds, the reliability of the platform is high, and the unman
