Mounting the Antenna NOTE: the mounted antenna must be at least 4 cm (1.57 in.) away from the nearest roll bar or metal surface to avoid radio interference. You can use the external antenna mount to mount your antenna in a more suitable location for your vehicle, such as a roll bar at the rear of your vehicle, to receive better radio reception. For the best results, use this method for vehicles that have a roll cage. 1 Screw down and tighten the antenna cable onto the Group Ride mount . 2 Find a suitable location for the antenna. 3 Using a flat-head screwdriver or 5 / 16 -in. (8-mm) nut driver, loosen the bolt on the external antenna mount until the ring separates.
4 Place the mount around the roll bar. 5 Tighten the bolt on the mount until the ring is secure. 6 Screw down and tighten the antenna onto the external antenna mount plate. 7 Route the antenna cable along a suitable path using the roll bars in your vehicle, and secure it using the included zip ties. 8 Secure any loose cable to the roll bar using the included zip ties.
