The invention provides a multi-frequency-band electromagnetic integrated mast, wherein, a satellite guiding antenna is in fixed connection with a top end of a centrally penetrating rod, and the centrally penetrating rod sequentially penetrates and is in fixed connection with a UHF1 communication system, a UHF2 communication system, an HF/VHF communication system, and an RF system; a distance between a bottom of the UHF1 communication system and a bottom of the satellite guiding antenna is 0.8~0.9 m, and a diameter of the centrally penetrating rod is 2 cm; a distance between a bottom of the UHF2 communication system and the bottom of the UHF1 communication system is 0.8~0.9 m, and a diameter of the centrally penetrating rod is 2.5 cm; a distance between a top of the RF system and the bottom of the UHF2 communication system is 2.8~3 m, and a diameter of the centrally penetrating rod is 3~4 cm; and a distance between the top of the RF system and the ground is 0.6~0.8 m. The multi-frequency-band electromagnetic integrated mast can cover multiple radio frequency-bands, thus improving an electromagnetic environment and enhancing systematic reliability, and can be small in occupation space and have modular design, thus facilitating multifunctional integration.
