JM008

The JM008 from Harxon is a 4-element integrated GNSS anti-jamming antenna designed to suppress broadband and narrowband interference in GPS L1 and BDS B1 bands, ideal for marine and UAV applications. It integrates a 4-element antenna array and a receiver in a single miniaturized, low-SWaP unit. This antenna is based on a dual-chip architecture that consists of an anti-jamming RF chip and a baseband processing chip. This integrated antenna can suppress jamming from up to 3 directions simultaneously and also supports anti-spoofing capability, ensuring stable signal reception. It provides a rejection of more than 90 dB (1 source) and 80 dB (3 sources). 

The JM008 integrated antenna has a horizontal positioning accuracy better than 4 m and a vertical positioning accuracy better than 6 m. It has an acquisition sensitivity of -141 dBm and a tracking sensitivity of -155 dBm. This antenna unit includes support for data protocols – binary and NMEA 0183 and configurable LVDS serial ports. It requires a DC supply of 9 to 36 V and consumes less than 9 W of power. This RoHS-compliant integrated antenna is available in an IP65-rated industrial-grade housing measuring 65 x 65 x 22 mm and has M4 mounting screws.
