The Type 408C is an operating in VHF-Band long-range air defence early warning radar system. The antenna consists of two horizontal polarized back-to-back 6×14 m wide dipole planar arrays, which can operate simultaneously at the high- and low-bands. Due to the low operating frequencies, the stealth measures of modern fighter aircraft are ineffective. On the contrary: due to the resonance of half the wavelength, the echo signals will be increased extraordinarily.
The radar is mobile with its units installed in eight operation vehicles forming four transport units.
