What is the amplifier and antenna for in the iCoach kit and will I need this all the time to operate it?
The iCoach router and radio will work with or without the amplifier in most areas. The amplifier and antenna shows the best performance and gives noticeable speed increase in areas that are far away from big cities or have reduced coverage. The amplifier also makes sure, while traveling down the road, you are connected to as many towers as possible giving you the best possible connection you can have in the location you are in.
