The directional panel antenna can be used for two applications. It can be easily mounted to a wall or chimney face, pointed in the direction of the closest mobile mast for maximum signal capture.
Alternatively the panel can be used as an indoor coverage antenna when connected to the output signal of your repeater. Since the panel antenn is directional it has a signal different signal pattern than a standard omni-directional aerial that would be supplied with the basic repeater kits.
This antenna is suited to indoor applications where you located the panel at one end of a coverage for a horizontal broadcast pattern inside the building.
