The screw-fitting part 4 is fixedly installed on the surface of the multi-channel spatial spectrum host 3. The upper array 8 and the lower array 20 can form the radio signal transmission of the second array element. Through the screw-fitting part 4, the rotating rod 9 can be screwed in and installed inside, achieving the installation effect of the horizontal array 10.

The end of the support rod 2 away from the mounting bracket 19 is detachably installed to the lower surface of the multi-channel spatial spectrum host 3 for easy transport and assembly. The first antenna 13 and the second antenna 15 transmit external radio signals via conduction. The signal is transmitted from pole 14 to the internal components of the multi-channel spatial spectrum host 3 for radio signal analysis, thereby ensuring the monitoring accuracy of the radio direction finding equipment. The internal devices of the multi-channel spatial spectrum host 3 send measurement task information from the receiver to the multi-channel digital signal processing board via display and control software. The multi-channel digital signal processing board controls antenna switching and sets parameters such as the frequency of the array receiver 17 based on the measurement task information. The multi-channel digital signal processing board processes and calculates the returned intermediate frequency signal and sends the measurement results to the display and control software. The multi-channel spatial spectrum host 3 mainly consists of an RF channel and frequency synthesis components. The RF channel performs frequency conversion, wide and narrow band filtering, and level control, providing the digital processing section with a fixed frequency, selectable bandwidth, and compressed level variation range.
