M9708CWT L1: GPS, GLONASS, GALILEO, BEIDOU L2: GPS L2C, GALILEO E5B, GLONASS L3OC L5: GPS L5, GALILEO E5A Part : 100-00138-01 Description The M9708CWT is an active multi-frequency, high accuracy, GNSS antenna for the L1/L2/ L5 GPS, Galileo, Beidou and GLONASS bands. The antenna is designed for applications requiring greater accuracy than L1 only antennas can provide. The antennas excellent radiation pattern, exceptional out-of-band rejection, minimal group delay variation, and low noise figure ensures optimal performance of GNSS systems. It features a 5 m cable with an integrated SMA, SMB, or MCX connector (customer choice). The M9708CWT is ideal for applications requiring minimal integration effort or for retrofitting existing prod - ucts and is rated IP67. The antenna is manufactured using automotive grade housing.
