An apparatus for displaying a received signal strength includes means for detecting a received signal strength of a signal received at an antenna. Coupled to the detecting means are means for automatically generating a display signal indicative of the received signal strength. The means for generating is configured to provide the display signal whenever the received signal strength is below a preset threshold. Coupled to the means for generating the display signal are means for displaying the display signal. The display signal may comprise a bar graph which is shaded according to the received signal strength. The bar graph is automatically displayed on the display means when the received signal strength is below the threshold.
