The CPG is a tough and durable 3G, GSM and GPS puck antenna with 2-3 dBi gain on the GSM/3G frequencies. It also contains a high gain active GPS patch antenna. The antenna is a screw-mount antenna requiring a 20mm hole. The exit for the cables (1 cable for GSM/3G and one for GPS) is on the underside of the antenna and once mounted is totally enclosed and secure. The antenna is secured in place by a nut that is tightened from underneath. The CPG is ideal for tracking,telematics and location-based applications where a discrete antenna is required, but rugged performance cannot be compromised.
